97 XJ 4.0. APN Header, 2.5 inch pipe to my high flow magnaflow cat, 2.5 inch to my super 40 flowmaster, 2.1/4 turndown before the axle. mine sounds great. Doesn't sound anything like a V8 but i am pleased with it. the turndown made it really loud inside, i may run it all the way out the back..

 

i run almost the same setup minus the headers and turndown

My flowmaster super 40 + 2.5" mandrel bent tailpipe + magnaflow hi-flow cat

 

my cat got clogged so i cut it of with the ol sawzal and got 70$ for it and now im running a quick replacement untill i scrap up enough for a hi flow cat

 

sounds good man

 

haha i mean strait pipes up to the cherry bomb aka no cat. lol you know what i meant!

 

me and my buddy got bored one day so we ran 6 inch tubes like youd run on a diesel on my parts cherokee. no cat or muffler. talk about loud and low

 

Wow how many adapters did that take lol. It was loud and low because of the exhaust resonance - with no pressure to force it's way out

 

.

I think this is more of what you're looking for, rin this on my Jeep, no drone, awesome sound $25

i have to partially disagree with this...true i dont think they have enough pressure to get the full end sound out of the 40 or 44 at that but i dont think they sound to bad or obnoxious on the I6

 

I run 2.25" pipe from the manifold to a SLP loudmouth2 muffler with a 2.5" tailpipe. It sounds pretty good and a little deep. It has no cat therefore is not driven on the street. You can hear the exhaust pretty good on this video

 

hey dukie the magnaflow cat you're running is it a high flow cat or the direct fit magnaflow or a universal fit magnaflow

 

yes high-flow magnaflow cat, direct fit (trimmed as required)

 

I use a high flow magna flow cat and a flowmaster delta 40. It's actually quite quiet if the radio is at 1/8th volume I can hear it except for hard acceleration. I absolutely love the setup. And there is no real drone that I've found. I drove 7 hours from ms to Texas and had no issues, barely heard the exhaust. Very deep growl too

 

Summit has some inexpensive to moderately priced "bolt on" cat-back exhausts, starting around $150 up to around $450. Do these things fit the vehicle as advertised?

I ask because a few years back I picked up a Hooker dual exhaust for my '72 F250 and it wasn't even close to fitting. Paid $150 for the exhaust and $150 to have an exhaust shop fit it up.

 

I bought my Dynomax cat-back exhaust with the tip and 2.5in piping for $75 after the mail and rebate. It fit quite well to me. It took maybe 20 minutes to get the old one off and 10 to put the new one on.
