exhaust question

So I have been driving my Jeep for 2k miles now.
Trying to figure out what's missing.
Got in my truck and I finaly figured out what it is.
I have a flowmaster 50 or 40 (I forget been 12 years after all)

So I was thinking of getting a new muffler and for it. Something that ties to the existing system just a swap out for better breathing and a little sound. Nothing crazy its a 6cyl after all.

Any computer issues to worry about?
Any one got some good sounding and increased performance stories they want to share.

Part number and prices etc are also helpful.

I want something better than a mosquito

There are a good number of different Cat Back Systems for you to choose from. If you go off road and want to relocate the muffler/tailpipe to keep it off the rocks, you can go with a system designed specifically to do that. If you're not worried about the rocks, you can find an muffler that will replace the OE one for better sound.

You won't pick up any appreciable performance gain from changing the exhaust, just the sound. But the good news is you don't need to do anything with the computer.

Hop on youtube and find a sound clip that you like. Then let me know what you're interested in and I'll get you a quote!

I agree!! Purchase a CAT BACK exhaust for the sound quality and looks. Very little HP increase. No code DTC issues.

I've gotta Flowmaster seris 10 cat -back and the sound is twice as good as the Flowmaster 40 cat-back was, but-

It's not in the stock position, it's all tucked inside the frame-

Flowmasters don't belong on anything under a V8. Get a glasspacked muffler like a Magnaflow or Borla...

This is my opinion of course... I've owned 25+ cars in my 15 years of driving, with every single one getting an exhaust... I can safely say that Flowmaster will sound like crap on a 3.8 Jeep.

Have the AFE 2.5" rock crawler straight line high-tuck. Moves the muffler from the rear high up under the left side in front of the axle. It's a nice 2 piece setup. No code issues. Under $400 too.

Hi jeepwrnglr92,

Glad to hear youíre interested in getting an exhaust system for your Jeep. Our cat-back systems at Borla will improve your Wranglerís performance, by giving it added horsepower and torque, along with better fuel economy. Not to mention the aggressive roar youíll get from our exhaust! All of our systems are made of durable, high-quality, 300-series austenitic stainless steel, which allows us to stand behind our Million Mile Warranty. If you purchase from us, it will be the last exhaust youíll need to buy for your Jeep.

I included a link below to our cat-back system (part #140479) offered for your Wrangler. Our retail price is $599.07, but Iíd recommend checking out Four Wheel Parts, Quadratec, JEGS, Summit Racing, or Amazon.com for competitive pricing. Iíve also included a video link of a JK with our cat-back system installed on it. I hope your search goes well & happy motoring!

Cat-back System:

I put a Flowmaster 50 series delta flow single in dual out after the y and put turndowns. No warnings and only ran $100 for muffler and about $60 for heat shielding and other parts. I like the some and not a lot of interior resonance. Will need to do custom pipe bending though.

So I am holding off on this and ding some more research into it. This is a low priority mod I think. Gotta save some $$ for a bit before I do any more mods.

If relocating the muffler wasn't a priority for me, I would have put a Flowmaster in place of the stock muffler. Flowmaster is first choice for me and Ive ran them on multiple 6cyl and 8cyl motors and all of them sounded great. I have the MBRP cat-back that relocates the muffler and am very happy with it on the 3.6, but I would take the tone of the Flowmaster over the MBRP. I would have had to relocate the EVAP canister to fit a Flowmaster in front of the rear axle though.

Here's a shot of the Flowmaster 40, which is gone now and I'm using the FM 10-great improvement and I used the same cat-back piping-



Good luck
