Price: $80.00
Pros: Increased HP/Torque. Better sound coupled with my new muffler. Price.
Cons: None.
Recommended? Yes

Comments: I contemplated on doing this along with my new performance muffler from Thrush for awhile. I finally bought it & had it installed the same day I did the muffler. The fact I did them at the same time makes it all that much better in terms of sound & power. Gas mileage has went up abit too. No CEL's or problems with anything. It is compliant with federal requirements & will pass emissions.

Price: $100.00
Pros: MO' flow, MO' power! Replaced my rattling clogged up cat.
Cons: None so far...
Recommended? Yes

Comments: Got this as part of my Iron Rock Offroad 3" Exhaust Kit. My OEM cat was rattling and I lost power. I had a local 4x4 shop install it and so far so good. I gained my lost power but dont think I gained any extra, even with my K&N FIPK. So I dont recommend it if your OEM cat is fine unless you just want the noise...

Price: $70.00
Pros: Cheap, replacement
Cons: Non so far
Recommended? Yes

Comments: Runs fine, got it on amazon for $70 so can't complain about the price. It was cheaper to go this route then to buy an oem replacement. I think I may have gained a mpg or so as the old cat had 240k on it. Was money well spent.

Price: $100.00
Pros: High flow(allegedly) stainless steel
Cons: none
Recommended? Yes

Comments: Seems like a pretty well made product. Got it to replace my factory one which was shot to hell. Price was pretty reasonable and a better choice than the $300 Random Tech cat I was looking at. I'd buy it again if I needed to.

Price: $130.00
Pros: Relatively cheap, solid construction, bolt in application
Cons: none
Recommended? Yes

Comments: Works great, purchased to replace my stock cat that was falling apart at 124,000 miles. Would have bolted right into place if not for the fact that the pipe coming out of the cat going to the muffler is 2 1/4", but I have a custom cat-back using 2 1/2" pipe so I had to get an adapter. If you are using a Magnaflow cat-back or any muffler that will fit directly onto 2 1/4" pipe then it will all match up fine.

Price: $200.00
Pros: Looks amazing, definitely increases flow
Cons: none
Recommended? Yes

Comments: Looks absolutely awesome under there. Stainless steel turned purple and colored after getting hot, looks real neat. Sounds nice, motor definitely runs cleaner and increase in power, better gas mileage too. Very easy to install.

I bought this with a Dynomax catback, and this kit came with the hi-flow cat as well as the downpipe. So i replaced my entire exhaust system at once (made it much easier. Get the whole thing in place (loosely), then position it as desired and tighten it down.

excellent product.

Price: $119.00
Pros: stainless steel, high flow
Cons: upstream 02 sensor threads got screwed up from improperly tapped hole.
Recommended? Yes

Comments: this system went in with not to much effort. had to cut the original cat and down pipe out with a saws-all since all the bolts were rusted in. went to put the 02 sensor into the upstream hole and ended up striping the threads on the 02 sensor. after i re-tapped the hole and replaced the 02 sensor it works fine now.

Price: $204.00
Pros: With my catback system, noticeable horsepower and torque increase. 50 state legal according to Magnaflow
Cons: With my catback system, I lost gas mileage intil I added an intake.
Recommended? Yes

Comments: The old exhaust was a pain to remove but the new one bolted right on in under an hour. When I first put it on I lost significant gas mileage. I also kept getting a trouble code for the rear O2 sensor which I replaced with the exhaust. I added a cold air intake and took the jeep in to have the trouble code checked because I didn't think my brand new O2 sensor would be sending the error. The shop replaced it with one from Jeep. So now, the trouble code is gone and I am back to factory gas mileage with extra power and great sound.
