Dual exhaust, I am in love!!

[Supercoolin]

Got my dual exhaust today, it sounds incredible. They cut out the wye and added short pieces over the cross member, then 2 1/2" x 6" flex couplings to a Dynamax Ulta X-Flo muffler w/ dual in-dual out, then a pair of 2 1/2" pipes over the rear end to 2 1/2" x 12" bullet resonators and dual rectangular tips. It is just mean sounding. I forgot my camera when I went to the muffler shop, so the pics are laying underneath the truck. I couldn't get a clear picture of over the rear end piping.

It was done by Performance Exhaust in Las Vegas for $900.00 complete.

Here is a video and sound clip.

If it helped performance, I can't really tell. The sound is so bitch'in that it makes you believe that it added +50hp, but honestly if it gave me 8 to 10hp, it was worth it because it sounds so great. It doubled the enjoyment of driving. I am like a little kid again.:D :D :D

Thats awesome, the quad tip set up looks nice on there. I love the sound too. Congrats!

[Dacomputernerd]

OMG!! That looks SICK!! :eek:

Edit- And sounds great too!!

[2002SLT]

That looks awesome and welcome to the site! :thumbsup:

[Blulytes]

Hotness!!!!

[terdrocket]

I can't tell if I like it, or REALLY like it. :)

When you get a chance, post a pic satnding a little farther back.

Looks good.

[1BADSS]

LOL..Racing into the sunset..Sounds good

[blautens]

From what we can see, it looks pretty cool....too bad you didn't have your camera when it was on the lift, though.

[scjzman]

That looks and sounds awesome. You still have your spare tire in place?

[sk_trailblaz]

Sweet ride...sounds even meaner :)

[trailblazingold]

Very nice I am always curious as to why chevy did the exhaust with one outlet on that machine.

[Supercoolin]

yes, everything is in the stcok location.

Sound level is not to bad on the interior. I haven't been on the highway yet at a constant cruise speed but I also haven't held my foot steady since I rolled off the lift!!!

:D :D :D :D :D :D

[ieatglue]

It's times like these I wish we'd gotten the V8. That sounds mean :yes:

[CIPNBREW]

Can you tell me wear you purchased the dual exhaust kit for the rear facial kit. Is there a prefered website that has after market products for the SS.

Thanks for your time.

The exhaust looks great.

It was custom cut for his application. There is no dual exhaust cutout kit available at this time.

[Z06 Tom]

That's just plain MEAN looking!! Welcome aboard the good ship Trailvoy!!

[vetruck]

Welcome to the forum Supercoolin and CIPNBREW :)

Exhaust looks awesome. I can't get the vid page to come up though:duh:

[Chris Foresta]

Im just stopping by again to take another look and watch the video another 5 times... man thats hot

[asphalt-hp]

I like it...:thumbsup:

[OurZoo]

Sounds f'in great! This is how GM should have made them sound from the get go.

[TonyGXP]

I was not happy with the single tip duals and the cutout...I really like the dual, duals..but I STILL say when someone puts a pair of megaphones on the dual setup it will resemble the concept and Look SICK....

[jordong]

That really sounds awesome. I'm thinking of driving up from Los Angeles to have it done. Can I get the phone number for them and who I should talk to? How long did it take to do the whole job.

Thanks

I just got the vid to work here at work, sounds great man. Do you have some shots from further back from the truck that you could post so we can get a real good idea of how it looks.

TIA,
Dave

Performance Muffler Shop (702) 740-5300

Installation was a team effort - talk to the Owner - just tell them you want the Trailblazer SS Duals - it cost $900.00 and change and took them 4 1/2 hrs. They will need to order parts so give them a call and set up an appointment. You might have to buy parts first with a credit card over the phone.

[dntnvme]

It sounds great :yes: , now get a tune if you don't already have one :D .

[ScarabEpic22]

Very nice setup, looks really mean!!

How is the sound level compared to stock, I know it sounds meaner, but is it louder or a LOT LOUDER??




And, all the dual exits for exhaust in the bumper are custom one-offs done by the owner or a shop. No one makes a dual exit bumper although I could probably do it and make some extra dough. The only thing is that everyone probably wants the cutouts in slightly different spots for their exhaust (ie single vs. dual tips, etc) so it would be tricky to do.

[blazerSS06]

Sweet sounds real nice.

[SSportWagon]

Duuuuuude :undecided :yes: :yes: :yes:

[chunn7]

That looks saaaaawheeet!! :yes: :drool:

[MyTBSS]

THAT SOUNDS GOOD! Just wondering how that setup would sound with flowmasters and no resonators? Wait aren't flows pretty much the same muffler as magnaflows?

[deathbynosleep]

looks great. That's how the SS should have come.

Crapmasters are no where near Magnaflow

Where do people get this info from?

[speederscout1]

Looks amazing, congrats on it! Really wish I had gotten the SS. But mine works for now, lol.

[jonathan]

great job! sounds like a flowmaster, does it pull harder? I am looking at installing one too.

why is magnaflow better? I like dynomax mufflers, what do you think about those?

[Supercoolin]

Dynomax Ultra X Flo mufflers are straight thru design. With the X Flo you have the X pipe built into the muffler for the additional torque and very very little back pressure. A single 2 1/2" Flowmaster will only handle 400 - 450 hp with no power drop because of the muffler. The Dynomax 2 1/2" X Flow will easily handle 550hp before you will see a power drop from the muffler (open vs. capped exhaust)

Flowmaster mufflers are not in the same class as Magnaflow and Dynomax striaght through mufflers.

Sounds better, better quality. Don't like Dynomax either. Gibson sucks too.

Only ones I buy are

#1 Borla
#2 Corsa
#3 Magnaflow

Ones I wouldn't mind trying

#1 ZOOMERS
#2 Stainless Works

[ScarabEpic22]

Well, as my Magnaflow on my TB is the only aftermarket system I have ever had put on, I really like the sound. Sure, its too LOUD for me (different than resonating), but I like the straight-through design of the muffler. Sounds like the dynomax muffler is similar.

I really like the X Flo part of the Dynomax:

You can do a proper dual exhaust in one half the lenght than if you used a Magnaflow and an x-pipe configuration. I couldn't have kept the flex pipes if I had used a Magnaflow and an x-pipe, not enough room under the truck to still keep it clean.

Looks great, much better then stock.

Yeah.......:iagree:

[2006 Blue TB SS]

Has anyone looked at using the Borla XR-1 series mufflers? They are rather expensive for a SS race muffler (might be too loud for some) but seem to have good flow properties.

There's a couple of guys with f-bodies that have used them succesfully.

[FULLXRACER]

WOW! that sound's and look's GREAT!:hail:

[Rube1966]

Sweet! :thumbsup:
