  • The performance 4.0L Jeep Exhaust IMO!
Excellent exhaust! Good quality and sounds fantastic. Its a mellow hummmm while driving and once you get into it it sounds awesome. Not loud and obnoxious, but smooth and powerful. I highly recommend it. The chrome tip looks great. Fairly easy install if your muffler/catalytic converter nuts haven't rusted away like mine did... I had to support the transmission with a trans jack, drop the transfer case skid plate and use a saw zaw to cut the bolt between the cat and muffler joining point. Once I did that which wasn't hard, just cumbersome. Would be a sinch with 2 people. (The skid plate is probably 60 plus lbs) . Definitely worth the trouble. It had nothing to do with Banks Exhaust. Its the rusty Jeep bolts. ... 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

  • This exhaust system had better reviews and contained better quality materials than almost any ...
This exhaust system had better reviews and contained better quality materials than almost any other exhaust system I looked at. There's no point in spending a few hundred more on MBRP, Magnaflow, or Borla when this sounds just as good or better. I researched for a few weeks before buying and watched youtube videos to find out which one I wanted. The differences were so minimal between the 5 systems I looked at so I looked up Jeep threads to see what people said. No one had any regrets buying this. The only requirement I had was that it be stainless steel. Not only was this stainless steel, but it was also the cheapest! I paid $220 for the setup and $50 to have this exhaust system installed. It took an hour and looks great with the stainless tip sticking out. The deep throaty sound was what I was going for but it's not overly annoying where people a block away can hear you. I will be buying this again when I purchase another Jeep in the future. ... show more

  • 2 thumbs up!

  • 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

  • Needs some fitment adjustments
Needs some fitment adjustments, but all in all sounds great. AMAZON IS NOT A AUTHORIZED SELLER, the oval tip didn't fit with my bumper so I contacted Banks and was told there was nothing they could do because I bought it from an unauthorized seller. Didn't know that so I'm spreading the word. I just left the tip off no problems. ... show more
