    • Fit a 2000 TJ perfect

Easy install, fit perfect on my 2000 TJ

    • Sounds better than a glasspack…
Just installed this “cat back” system, and it was very easy, and seems to be good quality. Sounds good, not too loud (I had previously installed a Magnaflow muffler that was VERY loud). I knocked off a star because the clamps included are not very good, and the muffler tip looks stupid to anyone over 15 years old. Other than those things, I would recommend this exhaust system. ... show more

    • Good system but a couple of flaws
I installed this system on a 2001 TJ with the 4.0L engine (286,000km) .Stock muffler was going and this kit was priced pretty reasonable for stainless.The picture shows a one piece pipe,it is two pieces in the kit I got.This is not a problem.Actually I got a better fitment with a two piece pipe due to the fact I could move it around to get a precise fit.I also bought a couple of Pypes HVC21 2 1/2 diameter 1" wide stainless steel exhaust clamps because I didn't want to use the two steel ones Banks provided with the kit.Liked the all stainless install (that's just me)The only issue you will have with the install is that the pipe comes pretty close to the passenger rear shock.I read in a product review in JP magazine that this was a issue so I wrapped some Therm o-Tech heat shield tape,around the shock, near the area.You don't want to cook your shock oil.This tape works great to protect against heat soak .From my experience with small block Chevy's and starter/header closeness this tape stops the nightmare for radiant heat issues.The sound takes a little getting use to at first but is pleasant after a while and there is no drone at highway speeds.There is definitely some increase in torque at mid-range and top end.I don't know how much,may-be 20 HP-20 ft.pounds on the butt dyno,but the old heap did get up and go a lot better!ONE YEAR UPDATE....I'm updating this review after more than a year just to give my impressions of the sound,durability,etc.First off the sound is as close to the sound of a 5.0 Mustang with headers than what I can describe...it sounds great!I'm a 60 year old fart and to me the muffler is a deep,mellow burble on downshifting and a nice subdued growl on acceleration.If you like to hear your engine then you'll like this system.The pipes have gotten a tad rust covered but that's expected because the nickel content can't be too high in pipes or they will crack due to constant heating and cooling,to me that's no big deal.The muffler is still shiny and the tip is a tad yellow.All in all for the money great system! ... show more

    • For jeep tj, sounds good. Will need a welder and experience for proper fit with no rubbing.
So, 1998 wrangler. No cats,, header with some more headwork. muffler and tip- extremely good quality, sounds absolitly amazing, aggressive as well, looks very good and clean. I'm not sure.. I'm just going to say it. The engineer on this project, got paid way to much for some halfa$$ work. Put in the correct year jeep and they sent me the muffler adapter for the other year. The over the axel pipe hangers appear to have been welded on backwards which causes the pipe to sit inch and half off, made it extremely difficult to put the hangers in the bushing and slide the pipes together. So it was either A keep the axle pipe off the shock, and the tap of the tip will have to be bend in and it will be smoothed against the aftermarket bumper that provides more room then the stock bumper or b- the pipe will rest against the shock to give the proper look. Next was the tallest part of the exhaist where it humps over the axel. About 2 inches too high so it would of rubbed against the heat shield, well we had to take that out to make the 4 inch adapter piece fit that we had to go purchase because the pitch was too high and it would of pulled the muffler back too far to put together. ... show more

    • Sounds great but install not easy.
I just purchased it a couple of days ago for my 02 Tj 4.0 5-speed, and here is my review. First off the kit doesn't look like the picture. The exhaust tip isn't a turn down but a big oval tip. I like it a lot better than the one pictured. The tail pipe coming from the muffler is not the one piece like the picture, but two pieces. I personally didn't like that aspect. That's one more joint to clamp. I had a tough time getting it all positioned correctly. In the end the tail pipe was way too close to the rear shock. That could be because I have a 4-in lift or some other variable. Because it was so close to the shock, I had to put a small relief with some heat and a 3-lb sledge. That I didn't like. The second to last step in the instructions state that the joints should be tack welded in addition to the clamps to prevent it from coming dislodged. I used my Tig welder to tack it all in place and I welded the tip rather using to clamp that was provided. Overall the installation was not as easy as I thought it was going to be. Now lets talk sound! I love it. It has a nice deep tone when you fire it up and it just sounds great going threw the gears. When you get to cruising speed it quiets down to a nice low tone. If I had it to do over again I would fully weld up the the entire tail pipe section that way I would only have one joint to clamp and tack in place. The shock and tail pipe contact might have been a deal breaker for me had I known. ... show more
