I just installed a Super 44 Offroad on my XJ and it doesn't quite sound how I'd expect it to. I have a hi flow Magnaflow cat that's been on for months. I also just have a turn down pipe on the muffler. I haven't customized a tailpipe yet. I was aiming for this noise:
Would adding a tailpipe, a tip, and breaking the muffler in make it sound like that? It's 2.5 too, btw.

Thanks

 

Mine does this. But it's straight piped Yes, 2.5" should help, possibly a tip. I've got a 4" tip but I never heard it without the tip.

 

Never been a fan of slow masters or chambered mufflers in general. I prefer a straight through style for aggressive tones or turbo style for a quieter preference but that just my 2 cents

 

What's a good tip? I looked at local auto shops and they're all chrome.. Is that my only option? Could I snag a better deal online somewhere? And I've been true straight piped before, but had a back pressure issue when it was hot out, so I went to a cat back, liked the idle and when I floored it, but the highway drone got annoying after awhile.


I liked how the Super 44 sounds, and it was less work for me to buy the Offroad edition.

 

I'll be going with a flowmaster 10. I am thinking 2.25" high flow cat welded to a 2.5" flowmaster welded to a 3" downturn tip. Does that sound Like it would work? The cat is 2.25 id so I would have to then get the flowmaster in 2.5" id then the tip would be a 3" id. Does this sound like it would fit? I guess I would also need a wider pipe for the o2 sensor hole. Where would I get one of those? Would the muffler shop where I will have this put on have one of these?

 

It's loud, just get a 2.5 magnaflow cat on amazon

 

Already have the 2.25" cat on with a 2.25 44

 

Slow master, I like that.

 

I have 2.5 cat and muffler its loud

 

Bump, the actual question is will the 2.25 to 2.5 to 3" hook up ok?

 

Ill help. Where are the connections being made?

The 2.25 > 2.5, you're fine. It's the 2.5 > 3" that is a stretch. Explain in detail how its being connected.

Remember, with 2.25" there is no performance gain. With Magnaflow, there isn't really a performance gain. It's 1hp iirc. The gain is in the 2.5". Now remember, with a gasser, unlike diesel, you can go too big. I feel, 3" is big for a 4.0l 190hp motor. You may loose power. So, again, where is the 3" going?

 

Go with a 2.5" cat, then a 2.5" inlet on muffler, with a 3" outlet. Then weld your turn down pipe. That's a better setup.

 

Glad you're not my neighbor. I'd have to confront you on that loud *** exhaust. lol.

Although, it does sound nice. The tail pipe cleans up the noise. If that's what you're looking for.

 

anyone heard a strait piped jeep? ive been wanting an exhaust but not a flowmaster, alot of people have them want something a little diffrent
