just to add to the fray my opinions

magnaflow muffler and hi flow cat. pipe in front of rear tire as said.
If I had extra money this is what I'd do to my jeep.

Right now I think it has the stock cat with some cheap muffler hanging off the end, (raptor i think?) like literally hanging with no pipe after that..... I'll be at least getting a pipe to come out the side soon and getting it secured properly. Need to fix the manifold gasket first since thats louder than the exhaust....

I have a cheap magnaflow on my 535, which is a 3.5 I6 and it sounds great.

No more discussion of the removal of emissions control equipment, in any way please, regardless of how it's worded. I don't want to have to close a thread because of this talk...

Aha finally the admin speaks up

magnaflow hi flow cats are legal everywhere in the USA except California and are a good upgrade

Yea, I want to get one but don't have the money right now and other things are a little more important at the moment. I try to fix what's broken before I fix what's working.

dont get a dynomax muffler they are el cheapo garbage I work at a midas and install them everyday and they are thin and cant take a beating

Good to know, thanks!!

I have all stock pipes with a Thrush Turbo muffler that was only like $35.00 and a very free flowing cat and it has been on there about 6 months and has gotten a little louder as time went on, about half as loud as a Flowmaster on the same motor but sounds really good in my opinion.
