Hey guys/gals! I'm looking at getting new exhaust, all ready ordered a cold air intake kit but my question is from the factory on an 04' GT, does it have 2.0 or 2.25 exhaust on it? I think it has 2.25 on it, but I want to make sure before I order these: http://www.flowmastermufflers.com/pr...oducts_id=3383

Also, let me know if you would go with any other style, if the style I posted will work with no issue's on stock cat back system and also if you think I should get the whole cat back system from flowmaster instead of just the muffs.

Thanks,

pretty sure its a 2.00 inch pipe. there is a big difference between my 2.5" o/r X and the stock pipes (more than 1/4")

2 inch pipe? um im pretty sure its 2.25 and aftermarket is 2.5+

yep

stock is 2.25, 99% of aftermarket has 2.5" pipes,, and tips go anywhere from 2.5 - 4"

Stock is 2.25" and aren't the delta flow 40s almost stock as far as loudness of sound? Original 40s FTW!

Hey man i got Delta Flows, i love the sound, also i have a Mac Hpipe putting it on tomorrow. Delta Flows aren't as loud on my cars but sound great!!! Hpipe will make it sound deeper. Also get 3 inch tips chrome, they look great!!! Factory is 2.25

Cool guess I'm thinking of the wrong mufflers, I cant wait to put on an aftermarket catted H to waken up my exhaust a bit more. I love the current sound, but can't wait to get it a bit louder. [sm=badbadbad.gif]

Thank you to everyone that posted. I thought they were 2.25" stock, but wanted to make sure.
