Comments: First mod, the JK was 5 days old. Very nice tone. Didn't notice a difference till I opened up the airbox. Butt Dyno says more responsive, Ear Dyno says 100hp increase!

Price: $147.95
Pros: Ease of installation. Comes with all needed parts. Puts out a great sound.
Cons: Can't keep my foot off the throttle due to the great new exhaust notes.
Recommended? Yes

Comments: I purchased the dynomax cat back exhaust to replace my factory exhaust that was missing all the hangers and had completely broken off in front of the muffler. The system was very affordable and it puts out a great nice rumble without being louder than the stock system under normal and hard acceleration.

Price: $144.60
Pros: Easy install, cost effective
Cons: Instructions doesn't point out that muffler is reversible.
Recommended? Yes

Comments: Based on the instructions (one small printed page) the system didn't fit my 97 Wrangler SE. However, after contacting Dynomax they stated the muffler is reversable, and then it fit fine. I find it MUCH louder than what was on this Jeep (may have not been stock, I doubt it was). I have a Draw-tite class 3 hitch and this fit fine around that. I have to bend the rear bracket slightly, but worked fine. I did NOT have to cut any of the tail pipe off. They must have fixed that issue.

Price: $90.00
Pros: Inexpensive. Good tone. Not much louder than stock but enough to tell it is there when you get on the gas.
Cons: Had to cut 3 inches off the tail pipe tip to fit like stock.
Recommended? Yes

Comments: Part number 19391. The 90.00 is the price after rebate. Bought on amazon for 165 and Dynomax has a 75 dollar rebate through 8/11. I installed this myself without help. I highly recommend having help to get the skid plate back on. Also the skid plate holds your tranny in place. I had a bit of a scare after the install before the skid plate was on. I hopped in and notice my stick shift had dropped 8 inches. All is well now that everything is back together. You'll need a deep socket to get the stock muffler off and the new one on. I couldn't get a perfect fit between the muffler and cat. I don't hear any air leaks but I see some condensation drips where it connects. Cut three inches off the tail pipe before installing. A local muffler shop did this for 10 bucks.

Price: $200.00
Pros: low cost, a little deeper tone than stock
Cons: Not really that loud.
Recommended? Yes

Comments: Needed a new exhaust due to New England road salt. This was a direct bolt on and went on much easier than I expected. It really came with everything I needed to instal which I tend to be skeptical of. It does have a great deep tone at higher RPMS's, so far I am very happy.

Pros: Super Turbo sounds great. Has low idle rumble, loud when on it, sounds like muscle.
Cons: Not stainless steel, still looks fresh tho
Recommended? Yes

Comments: Very easy to install, sounds great, great price, and looks very nice. The tip is stainless and comes out to the right, (OEM) however it doesn't dip, it shoots out on a 45 deg. angle. Fits with hitch on the back (with some bracket modification -bending).

overall great product.

Comments: Had to get new exhaust since my stock was rusting out, didn't want to go loud. So i went with the Dynomax turbo. Sounds good, doesn't sound like the crash up derby loud 6cyls you hear around town racing pizza around.

Price: $150.00
Pros: Sound, Quality, Price, Look, Bolt-On
Cons: Installation, Directions
Recommended? Yes

Comments: I really like the exhaust as for being "bolt-on", sure it is, after you hack off your old cat-back with a sawzall. Don't bother trying to bang it, pry it, or heat it off. If you jeep is like my it was spot welded like crazy. I guess its not really Dynomax's fault, but they try and make installation of their system sound like a piece of cake when really it can turn into a giant pain in the ***. Still a great product.

Price: $145.00
Pros: Nice for someone who is not looking for anything too loud. Interior noise pretty much stayed the same.A breeze to install.
Cons: none
Recommended? Yes

Comments: Great product. Easy to install. If you are looking for something loud then i would recommend another product, but if you want to keep the interior noise at almost the same level then this is the cat back system for you. Has a nice tone to it and the stainless steal tip looks sharp. Got it from summit racing and there is also a $75 rebate on it.

Comments: I bought the muffler and build the rest of the cat back. It flows great and I do think it will get louder with time, but it is still pretty quiet.

Price: $146.00
Pros: Low cost, Relatively quiet, Easy to Install
Cons: Tailpipe Sticks out a bit too far
Recommended? Yes

Comments: I just installed this cat-back on my 97 TJ because the old one was leaking. I had to cut the old exhaust to get it out, but the new one went right in. The stainless steel tailpipe is a bit on the long side so It could easily get caught up on obstacles. Simple solution.... I cut about 6 or 7" off the end and it is now about flush with my gas tank skid.
