I love the spintech 9000 with 2.5" piping. My XJ sounds awesome and there's so little drone I barely hear it over my tires. When I hit the gas though it opens up to a nice roar my dad likes it so much he's getting them for his mustang and bronco. They're great, well built and exceptionally small too.

 

I have a 1996 cherokee with a cat back exhaust system. its a flowmaster super 44 with 2.5in from the muffler back. So heres my question. my cat is completely shot(rattles like a ****) and i want to replace it with a high-flow cat and replace the pipe from the exhaust header to the cat with a 2.5in as well. which high-flow cats are the best? and is it a good idea to replace that exhaust pipe to a bigger size to make it 2.5in all the way? thanks in advance for the help.

 

Does the exhaust still crackle and pop a little? I'm looking into mufflers but I don't want tinny, or too mild of a sound. The straight pipe tends to wake up my friends' parents lol

Ok I'm looking at getting a cherry bomb glass pack, I have a 98 Cherokee, what angle and body length muffler do I need?

 

Crackle, no. It's a deeper tone. But it does still pop a bit when I let off the gas. Check out some of the videos on www.facebook.com/wny4x4club and look for ones of a red xj. Mind you, all those videos were taken on phones so sound quality doesn't do it justice.

 

Need a new system front to back. Know of any place that sells headers for the 2.8L.

 

I think gale banks actually makes a set for 2.8L V6 jeeps.

 

How do each of these change mpgs?

 

I currently run a Pacesetter header/downpipe, stock cat, flowmaster 40 muffler, then 2-1/2'' piping that dumps over the axle. I like the sound, but I want it to be louder. Im thinking about getting a 2-1/2" high flow cat, 2-1/2" cherry bomb glasspack, then having a pipe made that has it exit on the passenger side under the rear quarter panel(since I have the cut/folded lower quarters).

Anyone have this exhaust setup? or have the exhaust tip in the same area?

 

Split manifolds on a 4.0 straight six.. discuss. Are they even made for our engines?

 

Does anyone know what the size of the pipe is on a stock cherokee exhaust with a 4.0 engine? I want to replace from the cat back.

 

Thats what I'm trying to do, think its 2"

 

Yea, almost sure its 2" maybe 2.25

 

2.25 od
