another exhaust thread, few questions

[TrailBlazzin]

I know there are a lot of exhaust threads and I most likely read all of them.

I want increased performance and fuel economy.. I have a cai and tuned pcm which will be re-tuned for the exhaust. I want just a tad louder than stock on normal driving and noticeably louder when I get on it. I plan on removing the eye sore of a resonator and put on an aftermarket muffler. Looking into a magnaflow but I will take suggestions.

My questions:

What is the difference between the regular satin universal muffler and the xl series?
What size muffler should I get??
5x8, 4x9, 3.5x7 or 5x11 the XL only comes in 4x9?
Is there any other manufacture that has a product that will meet my needs better?


Any input would be greatly appreciated!!!
:thx

For what you want go with a 5x11x28 magnaflow. I would say flowmaster (love mine) but its fairly loud. Some people on here say that droning is an issue and all that, but I don't get much with my setup.

I have the Magnaflow 5x8x24 muffler on a 3" custom bent setup and it can get pretty loud at times. I shoulda went with one size larger but I may just get used to it. I like the noticable growl when driving around town and on the highway but when traveling around 35 mph, it is a tad louder than I like it...

i have a magnaflow and i love it people here you coming...how close do you live to delware because i got mine done at a good custom muffler shop the guy knows whats up i reccommend him PM if you want to know the shop

thanks for the input... what would the xl mufflers be like??

also do i need an offset/offset, center/offset, or center/center??

also 2.5 or 3 inch, are there really problems if you use 3 inch??

[tblazing]

it does not matter what offset you get it really makes no difference some people on here might argue it does in my experience it doesnt. as for the xl muffler i would imagine it would be larger than the normal one so it will probably imagine that it would be quieter

[TrailBlazzin]

according to magnaflows website...

the xl is not any bigger

whats the difference from the flowmaster 50 series SUV and 5x11x28 magnaflow??

main difference is that the flowmaster is a 3 chamber muffler, the magnaflow has some sort of packing. different sound altogether
