what do you think is better a cat back exhaust or a custom made exhaust with the same results of 2.5"

The results should be pretty similar as far as performance. IMO I'd say go with what's cheaper if you trust the shop your getting to do it...

well I was probably thinking of going the same route I did on my old vehicle I did 2.5" with a magnaflow exhaust with a high flow catalytic converter,thats all I was able to do with the old vehicle which was a 99 nissan altima it was really limited on parts honestly.

Personally i would get a cat back system. Its designed for specific sound and performance and will work well every time. IMO cat backs have a nicer tone to them anyway. But if you think you can get the same results and know how to get it done then go for it.

i got lucky and got the GMPP Performance cat-back when it was $360. best mod to my car so far. love the sound. it's really up to you. i've seen a few custom exhausts. like stated before: if you trust the shop and they know what they're doing and it comes out cheaper, go for the custom.

well I actually got a free estimate today and it will cost me 180 dollars to do 2 in half piping for the exhuast,also from what I believe the guy said for 180 dollars he will do the header and downpipe as well,including the exhaust system and muffler.I think that is one of hell a deal

the guy is going to call me on Friday actually,he didn't have the book on the dynomax mufflers so he said he is going to get another one and let me know,or I will go to murrays and grab the muffler which is the dynomax super turbo version,honestly wont make a difference but I believe murrays usually has that stuff for 10 dollars less

I would go with the cat back simply because it was most likely they are built with mandrel bends. The custom shop wont have that kind of equipment for cheap.

manderal bends are slightly over rated and you can compensate for them with extra diameter to a certain extent.

I would go with a custom full exhaust over some name brand cat back. A cat back will give you only minimal gains if any at all, where a full exhaust will yield you some nice gains.
