Had my mechanic install this in about 30 minutes I’ve had a small yet noticeable increase in power. I was hoping for around 10-15 hp increase and I think it’s in the ballpark (Did have leak in exhaust before). Sounds good too, nice low smooth sound. I would recommend.

Really tones it down sounds good at speed,but between 1000& 1500 it sounds like I have a low rod knocking. Not for a 4 cylinder

Installed in March 2015. As of June 2017, the exhaust started falling apart. I have lots of leaks on my muffler and haven’t beat it on anything. I will be trying out the kit from Magnaflow next, instead of another Dynomax.Look at my picture I added. When I removed the system today, my pipe fell right out of the dynomax muffler. No wonder I heard so much leaking. I will not recommend this one, and I live in Texas so my climate isn’t crazy.

Installed on my 92 Jeep YJ. Fit perfect on the factory exhaust hangers. The sound was better than expected. For the money this is a perfect upgrade to a Jeep YJ.

Sounds great on my 91 yj. However the hanger on the muffler was much longer than I expected causing the muffler tip to look way too low. I need to modify it to look right.3 stars becauaw package had clearly been tossed in the bag and clamps were not included. However they did refund me the cost of the clamps.

Looks nice and bolted on easily enough. Just thought it would sound a little throatier than it does. Over all ok, you just wont get that rumble if thats what you are going for.

Didnt use the supplied clamps, I welded this kit in place on my 94 YJ. Very happy with the quality and fit. Muffler is slightly louder than stock.
