Loved it really easy to install and sounds great just wish it had better looking hangers can see 2 of them fron the rear and they don't look so great

Little louder than expected
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.
By Ralph from Indianapolis
sound changes with RPM
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.

Sputter, Sputter, Spit!
The duel exhausts add that racy look to my Jeep.
I had to use tie wraps around one(pass. side)mounting hanger on the Jeep as the hanger on the muffler does not line up with the OEM rubber hanger. I might try a stainless steel hose clamp to secure it better. Also, had to remove spacer blocks on clamps in order to tighten them enough so as to secure the muffler to the engine exhaust pipe and the tips to the tail pipes.

Good quality and the price is right
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.

Looks good & sounds great
an hr. after it arrived it was on my JK. the sound is just about the way I like it. I believe it has more power, in fact when I hit 2nd gear the rear tires chirped. That's a first! Now to the strip.

One hour Job
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.

Sounds Pretty Good
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!
2006 Chevy Silverado 2500HD. My name is Jonathon, I am just wondering since this is single exit and also a straight through muffler, will this make my truck pretty loud (I want it loud)?! Thank you! :)
