Only Mod I have removed after 200 miles…
PROS: Seems to give you a little more pep in the pedal and my gas mileage went from 18.3 mpg to 18.8mpg. Lastly, was ease of install-took me 20 minutes.
CONS: The sound on take off is great, but at highway speeds, every time the automatic trans shifts from 8 to 7 and if passing 6, the sound in the cabin is suddenly very loud. So loud, conversation has to stop and you sit and wait for the trans to shift down. Because 85% of my driving is highway I removed.

Moral of the review is if you want a nice Rumbly Wrangler, this is perfect for you and you’re gonna love it. If you drive on the highway a lot, consider the volume before purchase.

Both exit exhaust pipes where the tips attach to are bent and it's impossible to slip on the exhaust tips. One is even dented inward and totally deformed. Also the included exhaust clamps are super flimsy and thin. No way they will last long especially the one that attaches the main pipe to the Stock exhaust. I guess you do get what you pay for. I will return it for a Magnaflow or Borla.

I am very disappointed with this product.

The exhaust does not have a notch to fit into the stock mid-section of the factory exhaust. Also, the included clamp is not strong enough to squeeze the exhaust around the factory mid-section to seal against leaks. I had to purchase a more robust clamp to install it correctly.

The exhaust does not hang correctly from the factory hangers. This caused the exhaust to be held against the rear bumper. I had to purchase different adjustable rubber hangers to separate the exhaust from the rear bumper. No adjustment of the exhaust would get it to hang evenly; the integrated hangers are not even, so the exhaust does not ride level.

After 500 miles of use, the black coating under the exhaust is all but gone. On top of that, the "Quadratec" name on one exhaust tip differs. Meaning one side is legible and one is not. This is not due to use; one is etched differently.

Overall, the exhaust is crooked, the coating is wearing off, and the installation requires additional parts. I would not recommend purchasing this exhaust.
