Reviews: Dynomax Stainless Steel Axle-Back Exhaust System - 39510

Modifications had to be made to factory exhaust. Pipe must be shortened to fit. Brackets on muffler also needed to be modified since they were bend incorrectly. Once installed though they sound great and look even better with the dual exhaust.

Exhaust was very easy to install except clamps were not able to tighten down on tips. exhaust was a little louder than I had hoped.

I have a manual trans. At 2500 rpm the exhaust is a little loud. My 14 year old son likes the sound. At all other RPMs, I can barely hear it. Nice subtle tone at those RPMs. I had to bend the heat shield a little to avoid contact.

Best price out there for a duel exhaust set up. Good quality matierials and all the bends are correct. Easy install, direct fit replacement for your stock muffler. The system would look better if the muffler was the same width as the stock unit and seperated the exhaust tips farther, while also making the tips a larger diameter. The clamps break easy, so don't overtighten them. Over all, I'm pleased with the product.

Took about an hour to replace stock muffler. Hardest part was removing the stock muffler. I used silicone to add in removing the hangers from the rubber mounts, this really helped as they are not that easy to remove otherwise. New dual muffler look great and sounds good too. Not too loud and no drone noise in cabin. Price was right.

Went on easy, sounds good, with the exception of a little backpressure grumbling and having to trim the heat shield due to rattling. IMO looks better without the tips installed!

Bought this for my 2008 Wrangler JKU. It was supper easy to install. Everything lined up and had it on in about an hour. The only issue was getting the old one off cause the clamp was rusted.. Used my Dremmel and it popped right off. I get great response with the new muffler and since the jeep 3.8 engines aren't so great, this was a nice improvement. Plus I notice I'm getting about an extra mile or two per gallon. Love the throaty sound this muffler has too...my wife unfortunately is not a fan, but she doesn't drive it anyway....
