Hi all, I am new to this forum. I am looking for a high performance modification for my 2003 Grand prix se 3.1 LT. Does anyone make a cat back system for a 3.1 V6?

Any other modifcations that can be done without swapping to a 3.8

Thank you

Cat back will net you zero gains in performance. Not much out there for the 3.1l check out if iirc there is a forum for 60* V6s. Youll have to google it. But for the cost to get any gains Id spend tbe money on appearance mods then money for mods on the 3.1.

Welcome aboard! A good bang for the buck mod would be a Magnaflow downpipe & hi-flow cat: Magnaflow 23433 (aka a direct fit converter)

You can submit a "best offer" price, and get discounts of up to 35% on K&N intakes.

For cat back exhaust, a 3.8L one will work, but you'll need a hanger for the driver's side muffler. Palsut installed one on his SE: my new dual exhaust *add video for sound*

Here's a couple of places to check out: http://milzymotorsports.com/ and http://60degreev6.com/

thank you, this is very helpful. i will look into it.
