lol... I assume you mean as opposed to "clanging"

 

Lol yep exactly. Kind of miss the clanging now since I listened to it for so long

 

Planning on replacing the whole system from the manifold back. From the mountains of pages I've read, unless the manifold on the 99XJ is leaking, I might as well just replace the other pieces. Let me know your thoughts on this.


2.5" pipe from the collector to a 2.5" Walker universal CAT, then into a Dynomax 2.25" system for the XJ. Thinking of adding a flex joint between the CAT and Muffler.
Opinions?

Walker and Dynomax are owned by my company, so it's 50% off for me. (as well as Rancho and Monroe)


INFO: 99XJ has 96K, big factory CAT can hanging low, and the exhaust was cut off just before the rear axle. (kinda fume-E, but no stock header leaks detected)

 

Just welded a 2.5" In/Out Flowmaster Super 40 on my 2000 XJ, and decided to keep the back cat. Ended up not being as loud as I would like. How much louder would cutting the back cat out make my exhaust? I dont mind inside noise.

 

You should go read the forum rules.

 

x2.... and BTW not worth it at all - considering it's illegal

 

If you replace it with a higher flow cat, it will get a little louder.

 

Would a walker glass pack resonator double as a minor muffler? I heard it gives a deep throaty noise rather and is sturdy. Is it any good in the first place?

 

Magnaflow straight through muffler on my 4cyl. Sounds like a tractor.

 

I'll check it out after school. Does it have that deep throaty noise that's so sweet?

 

The cat-back exhaust I'm looking at says it will not fit models with a welded hanger on the pipe. Is there a way to get around that? Can I just cut the hanger off and have a new one welded on?

 

Also, can a muffler that broke off of its weld and is suspended between the cat and exhaust pipe cause me to fail a smog check (high NOx readings?)? If so could spot welding it back on as a temporary fix work?

 

Could I buy this: http://performance-curve.com/84-01ch...5tailpipe.aspx, get a high flow cat, and take it to an exhaust shop and get it all put together? Would I generally save money buying it this way and supplying them with most of the parts? Sorry, new to exhausts.

Assuming I'll need a down-pipe and downstream o2 bung welded on the cat I buy as well? Have tons of exhaust leaks and want to get it sorted. Plan on replacing stock manifold with headers down the road as well.

Edit: Also want it loud. Don't want mufflers. Going to get a catalytic converter even though in Alberta I don't need to. From what I understand a downstream o2 sensor plays an important role in 98 cherokees unlike some earlier years, so I would like to maintain proper function and not have a CEL all the time, thus I will keep a cat in the system.

 

Hehe.. heck yeah it does. Kinda reminds me of the old hurricane motors - unmuffled.

lol... wha? 'snot a v8

 

True.
