New exhaust system questions.

Looking to replace my exhaust system from the headers all the way back to the tail pipe. So I am just gathering info for my 95 wrangler, 2.5L.

Do I have this right, in order?

Headers http://www.quadratec.com/products/17601_502_07.htm


Front pipe http://www.quadratec.com/products/51409_06.htm

Not sure about this next part, about the "Cat-back system". I assume it's everything behind the cat? If so then I would need something like this...

Then would come the cat back system..

Not really concerned with the product type at the moment, just want to make sure I have the order of the exhaust system is correct. Any input on what is the best product type/name brand to go with for exhaust feel free to pitch in. Thanks,

Sgt. Scotch.

You are correct in surmising that a cat-back system does not include the cat.

I recently replaced my cat and cat-back exhaust. I went with a Magnaflow cat and an OEM style cat-back from Walker Exhaust (alias - Dynomax in the 4WheelParts catalog). The kit has the QuietFlow SS muffler which is mellow in tone, just a tad deeper than stock. This is probably the equivalent for your 2.5L Dynomax kit. Probably performs just a little better than stock. Inexpensive too.

Searh this forum before you buy. I did a total exhust replacement on my 95 about a year ago. I purchased everything from Qtec except the manifold, which I got at A1 autoparts.

The head pipe (between manifold and cat) I purchased from Qtec that would not bolt up to a OE manifold. Several other posters had the same issue with the headpipe from Qtec. I purchased a headpipe from Napa at 1/2 the cost and it worked great. So my exhust is as follows:

Manifold (OE, not sure of brand)
Headpipe - Napa
Cat - Magnaflow
Cat back Gibson.

All working well

Thats a great way to blow $387 needlessly, but if you got the cash, go for it.

That is some good intel, thanks! Kinda along the lines of what I was looking for, I was unsure about the head pipe just by looking at the pictures. I'll give napa a ring tomorrow and have them order one. Thanks.
