Now this truck sounds like it has 400HP and backs up the SS badges :yes: :D . My performance oriented personality got the best of me today as I just couldn't stand how quiet the stock exhaust was , so I went to Mufflex custom exhaust shop in Trenton , NJ to see what was worth changing on the stock system , first they took off the stock muffler and checked it out , and while it is straight through , it does have a bend in it at the end , and the baffling and sound absosrbing material is probably hurting flow a little bit , I did this mostly for a more performance sound than for horsepower , so they put a Magnaflow on it and I took it for a test ride on the highway , the truck was still too quiet , barely louder than stock , so back it went on the lift and off came the stock resonator , when I first started the truck with the resonator off , I knew right away it was the sound I wanted , it's not too loud on the highway or at cruising speeds , but when you get on it , it sounds awesome , I think I could best describe it as loud enough to turn heads , but not too loud , and not even close to obnoxiously loud , in fact at cruising speeds its quieter than my old 5.3 Yukon that had a magnaflow and dual tailpipes . Performance wise it does feel more reponsive and a bit quicker , it is definitely breathing better than the stock system .

I plan to run the truck next weekend on opening day at Raceway Park , Englishtown in NJ , so if any of you local guys will be there you can check out the sound for yourself . By the way , Mufflex had a brand new red Jeep STR-8 in the shop yesterday getting new mufflers and the resonators deleted so those Jeep guys aren't just going to sit back and leave those beasts stock either , maybe he'll show up at the track next weekend and we'll have some fun .:D

Which magnaflow did you use?
Can you post or send me a sound clip?

Thanks

yah 5x8 or 4x9 case

14case /20 overall length
orrrr
18case /24 overall length

im doing a 3 inch mandrel bent set up. Thing is im wondering if the magnaflows will drone in the truck.

I'm not sure which Magnaflow it was , it is still a big muffler , only an inch or two shorter than the stock one . I'll try to find out Monday or you can call Mufflex if you want . www.mufflex-performance.com (http://www.mufflex-performance.com)

Any chance you can give us more specifics of the stock exhaust? Like the ID or OD of the stock piping? Did you replace any of it? How about that flattened piece of piping over the axle?

How about that flattened piece of piping over the axle?The stock piping changes from 2-3/4 at the inlet of the muffler to three inch coming out , I didn't want to mess with the over the axle pipe , because of clearance issues and we didn't have time today , overall I think there is minimal power to be gained with replacing the muffler/tubing , maybe 5-10hp , like I said I went more for the sound aspect , although if you put headers on the truck , the rest of the system might be more critical , I'll see what kind of gains the headers make , and then I'll cross that bridge .

so wait from the muffler back its a true 3 inch set up. It doesnt taper down to 2 3/4 going over the rear axle.

your saying the muffler is 2 inhes shorter than stock?? the next size for the magnaflow is 24 case length and 30 overall length so i think thats what you used.

now there is no drone you said im wondering if i went with a shorter muffler which im planning to do wonder how much louder it will be. Is the stock tbss exhaust stainless steel or aluminum

thanks man

tonyThe stock exhaust is stainless , the system is 3-inch out of the muffler then it does kink down over the axle and then goes back out to 3-inch , but the guys at the shop do alot of f-bodies with their kinked up y-pipes and they never saw a gain in times at the track from replacing the kinked up y-pipe on those cars so they didn't feel it was worth replacing the over axle pipe , it's hard to say if it would make a difference , if it was a 700+rwhp car then yes , I would definitely have mandrel bent all the way through .

yah i got a email back from the shop. they said theyu used a 5x8 muffler in your truck just trying to figure out what length. also they said they used "a custom resonator eliminator " which im guessing is just cutting off the resonator and adding 3 inch pipe in its place.

now you can hear the exhaust but it is a little loud at all when you romp on it or is it fairly quiet still

thanks

e bay muffler is 84 shipped
and to have a shop cut off the resonator and put a pipe in and weld the muffler in out here is 30 bucks.

im saying at most 120 bucks and that includes the muffler

I Do think the trailblazer ss has a offset entry/center exit muffler. the 4x9 case will be much louder thats why a 5x8 case is better to go with.

here is the one im planning to install (5x8 case)
20 inch overall length 3 inch offset entry/center exit

the one that is 2 inches smaller than the stock one is this one (5x8 case also)
30 inches overall 3 inch offset entry/center exit 3 inches

a couple of us were already planning to go to Eng.Town this weekend (waiting since last month when they released their 06' schedule!) so I am sure we'll see you there, sounds like you're waisting no time seeking out another 9sec vehicle??:eek: .... I bet this is how the vette started out isn't it??

I am curious about one thing.. you say the stock muffler was straight through and only had some baffling inside, also the resonator, yet you claim a HP advantage? I personally will not do the exhaust until headers/highflow cats, Etc. have been fitted. (I understand you wanted a better sound) I just don't think you would gain even 5HP from what was done, which is why I am waiting for the whole exhaust... Truck has a hi-flow (for factory, anyway) muffler/resonator and 2.75" pipe into 3" already..so would you say this a sound only mod, or do you believe there really is a 5-10hp gain? these engines seemed to be more restricted up front (manifolds), at least the claimed/confirmed (dyno's I've seen posted on the other sites, albeit GTO/Vette LS2's) HP gains from a header install would lead you to believe that, so how much more freely would /could it flow if the exhaust isn't getting out of its own way to begin with? don't mean to be skeptical, just in my nature, when the majority says otherwise..

When I get an exhaust, as long as I do it all at once I think I'll be able to weather the storm, so to speak, and after that it will be fine (until one of her girlfriends hears it..)

Sorry, I am a little late on this convo, but... I have the magnaflow catback installed. It is a little quite, but I kind of like it that way :suicide: . Ok I want it louder. I have thought of deleting the resonator but I am afraid of a few things: Loss of torque (maybe, I dont know, less back pressure?), Too loud, and Interior drone. Since you say there is no interior drone:undecided , I am just wondering how loud is it really? I had a Borla on my 98 SS Camaro and it was perfect and sounded great (nice note to it). How would this compare? and my biggest concern would be... How does it sound? Does it sound HOLLOW? or is it a nice deep note or somewhere inbetween? Long story short, I want it to sound like an LS2 not a 5.3 with loud exhaust. In the end.. it must sound like a vette (minus the whole dual exhaust thing...:drool: Thanks for your help!

yah the magnaflow is way to quiet. If you put a smaller muffler would be louder but honestly it sounds whimpy from the clips.


what is the muffler size on that set up anyway that magnaflow does??

id just cut the exhaust where it goes down after the axle and see how it sounds. If its to loud put it back and put in a smaller muffler

what im doing is gettin the magnaflow 5x8 case and 24 overall length with 3 inch pipe all the way back.

i think they're used to it. i have a harley with pretty loud pipes and it doesn't seem to bother them. my wife thinks it's cool and my boys really like it.

So you're saying there is no muffler on there at all now, just pipe and tip?! Doesn't the engine need more backpressure than that?

i aked the same questionand they pointed out that there are two, forgive me I've forgotten what they're called, near the engine that create the needed back pressure. if you go to the ss gallery and look at the third picture you can see them near the front of the vehicle on the inside of the frame near each fron tire.

WOW, that sounds great!!! I really like the interior sound, but the outside one is a little loud for me. I think it would be better to hear it in person, as each persons tastes are different. But, overall good job! I would remove the resonator ASAP when I get one.

Would that be the oh so familiar key chain knocking into the steering column that I hear in the first clip? That gets on my nerves:mad:

Well guys, just had the resonator removed and all I can say is OH MY GAWD!!!! this is how it should have sounded from the start.. Fred, if you want to hear how it sounds, PM and maybe we can meet up. This truck sounds SCHWEET!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!:thumbsup:

They had to use a new tip, the old one was to small for the new pipe. Got the double walled Magnaflow 3 inch tip for 20 buck, out the door was $120 complete. took an hour to do.:drool:

Other pics in my gallery

Resonator is straight through;

For you guys with the rolled tips, just an FYI... Keep that thing clean and waxed all the time. Those rolled tips do not all moisture to escape as well and that little drain hole does not do a great job. I have heard of those things going bad in 8-10 months from corrossion etc. This from my muffler guy.

the guy who did my exhasut also warned me prior to making a choice of tips. good info to pass along.

OK, after reading the posts to this thread last week, and sort of wanting a more "performance" sound, I had the resonator removed. I had the existing stock tip re-attached, so it keeps a completely stock look (the tip matches the trim panel contour). The sound is as everyone else says, "what the truck should have sounded like from the factory". Not too loud, but loud enough, and it does have a nice tone. The removal of the resonator cost $60.00, and I'm happy, :) for my money this is enough, until someone comes out with a complete system with headers.

Well I finally found a shop that didn't want $100 to do do this so its over there right now. $40 for the swap and keeping the magnaflow tip on there. We'll see... I have a feeling it is not going to be that much louder. The guy even said something about how big the muffler is. He says he puts them on all the time, they are straight through and flow great, they are just not very loud. Its a long muffler:duh: . I'll let you know it sounds in just a little bit.

You're getting the 22" (28" overall) 5 x 11 Magnaflow put in place of the stock muffler? Or did you get the 5 x 8 version?

Can you do me a favor when you pick your vehicle up and look at the stock muffler and see if it is straight-through? Pictures would be great - Thanks!

Actually, I already have the magnaflow catback on my car. It is a 3" catback with a Magnaflow muffler (don't know what size, but it is very long probably close to 30" long) and magnaflow resonator. All I did was cut off the Magnaflow resonator and put a peice of pipe in its place.

I got it back and it definately sounds better. Still very quiet at idle (probably because of the size of the muffler that is on there) but sounds much better and 100% louder at WOT. Definately $40 well spent!! :thumbsup:

im finishing up my sound system this weekend then next week going to the exhaust shop on wed. I have 2 8 feet pieces of straight 3 inch stainless pipe (ill prob sell what i have left over) and 3 inch mandrel bent 90 and 45 degree turns. The magnaflow is a 5x8 case with a 24 inch overall length. Ill see how it sounds and get a clip. My sony takes pics but for some reason wont take videos.
