Yea thats true but there is no need for big cat-back exhaust the best thing is just open up the rear section. Stock the midpipe is 2.25in, then the rear section is 2.0in. Just add a vibrant or another aftermarket exhaust it would add a couple of ponies instead of spending like 300 to 600 dollars on a exhaust for an srt-4 that is 3in wide.

It would just cause to much back pressure.

 

they are 4in exhaust's and you gatta admit those big pipes look NICE.....

 

yeah I love big exhausts like the injen and greddy also for single exhausts I love the hks has a huge tip and the exhausts on the new caliber srt4s are nice and big and single exit. All the bigger exhausts are mostly stainless steel also the best way to go with any exhaust.

 

Wow; All the interest in the Mopar Borla exhaust. I just sold mine recently. My Mopar Borla exhaust was really loud when I got on the pedal.

 

I have had my borla for about 6-7 months now havent got stopped by cops yet and I think my car is loud
