Great product with one slight design flaw....

97 TJ Sport 4.0L...Got this setup to go with Banks Headers (51327) and Banks Monster cat back (51312) as my old headers and midpipe from previous owner had a custom welded setup. Super happy with quality. Knowing i have Magnaflow as part of my system is piece of mind. Beautiful quality and once all together, sounds wonderful. Here's why i didn't give it 5 stars..the flange that mates up to header is recessed. On the side of downtube that bends in, you CAN'T get any socket (even a 1/4" drive) or a box wrench on it. You have to angle down with a box wrench and try not to strip anything out. I've included a picture. A simple flat flange would be perfect (Banks headers had it). Pipe was way to close to driveshaft, i was getting a nasty clunking on decel during first test drive. A simple loosening at header and cat, spacing with a block of wood, and re-tightening, fixed the issue. I would definitely buy this again!!

Highly recommended catalytic converter..

I had to have the downpipe fabricated to fit, it was hitting my front driveshaft. The cost for the mod was only $70 and I am blown away by the way my Jeep TJ runs now. I also added the Magnaflow well as 2 new O2 sensors. It is worth the investment, you can tell a world of difference in power, it's like adding life to the 4.0 liter inline 6. Highly recommended for all around conditions...

Does not fit Wrangler 2.5L

I was disappointed that this product does not fit the Wrangler 2.5L as advertised. The manifold flanges are not in the same locations. This kit also comes with a 2.25" flange but the 2.5L only has a 2". Wish I would have noticed this before I cut my old exhaust off. [...] Instead I contacted a local exhaust shop who was able to weld on a new flange at the correct angle/size for only $40. [...].The product itself looks outstanding; and coupled with a Monster exhaust my lil' 4 banger has a little more pep in her step. I only rated it a 4 because of the false advertising.Invest in a good set of band clamps unless you want to have a local shop weld them up for you. The kit comes with only u-bolt clamps.
