2.5" vs 3" cat back

Unless your running rediculous hp , it isn't needed. Less backpressure will be a slight factor in low end , but might help slightly in the higher rpms.
Some say the 3" systems tend to be slightly louder than the 2.5" systems

i think the 3" is probably a little deeper. id go with with a 2.5 i know guys with kb's and whipple's who run 2.5. if you get an aftermarket midpipe thats 2.5 all the way so thats pretty good.
+1. Only reason I went 3" was I got a good deal on it. The exhaust note is typically deeper and I really didn't feel a bottom end loss although I'm sure I lost a bit of torque. It will all come back with the 2.76" :rockon:
The bottom line with exhausts is they all produce about the same power so find the exhaust combo that sounds good to you and go with it.

i have the mac 3 in. with h&r race springs and i scrape on pretty much everything not sure how much a 2.5 exhaust would differ
i sport a custom 3 inch catback with dynomax muffs, this is all bolted to a stock h and it makes great power with a stock H.. but as soon as i threw the off road H i could no longer scratch 2nd gear... if you keep the stock h.. i 3 inch catback will help with power and not hurt anything!! i got the numbers to prove it.. peace
I also have Mac 3" the fitment on a 3" catback is horrible. I had to take it to a muffler shop to get the tips straight and had to have the bends modified to clear the gas tank.
It sounds MUCH deeper than other cobras. When paired with a UPR offroad x, the rasp + the deep Mac exhaust note = sex!!!!!!
TRUST ME ON THIS

i run the m55 s full 3 in and i think it looks a lot better than a 2.5 in.....jmo..oh and i think they are a lil louder..
+1 on this. I have Bassani midlength / or xpipe with Mac and I love the deep rumble plus the rasp when I get into. Nice and loud. :banana:
