1997 3.8L Cougar Catback? July 18, 2008, 11:57:28 PM So i don't exactly remember where I read or heard this, but apparently this catback from Dynomax http://www.jegs.com/i/Dynomax/289/17379/10002/-1/744690|10249# can be fitted onto a 3.8L 97 Cougar XR-7. Anyone have any experiance with catbacks on a 3.8L MN12? Also, if you know of any catbacks which claim to bolt on to a 3.8 let me know, I've had no luck in finding them. Another thing I've heard is that an exhaust system that fits on a 94-98 3.8L V6 Mustang fits on a 97 3.8L Cougar. Doesn't quite sound right to me, but do let me know if there is any truth in that.

Reply #1 – July 22, 2008, 12:34:39 PM Never tried the cat back but you can probably get one made cheaper at a local exhaust shop.The Mustang exhaust will not fit your car as it has a different chasies. Also any exhaust mod to a 3.8 might, might get you 10 hp. Don't expect it to be a monster after the exhaust is done..... Quote Selected

Reply #4 – July 23, 2008, 11:15:09 PM Yeah, having a glasspack is practically not having a ler, its pretty bad, but I would like the old cat to have a little bit of a deep roar if you know what i mean :-PI'll be getting it in a week or 2, then have a shop i know try to hook it up. Will post an update for anyone who may be curious Quote Selected
