Easy Install

When I purchased this exhaust, I thought I was just replacing the tailpipe, which rotted off at the muffler. After looking at the system and reading the instructions, I realized I had to delete the muffler. The instructions refer to their muffler, which was not part of the kit, so I was concerned about the sound. The system was an easy install, having only to cut the extension pipe to fit my wheelbase. To be honest, can't tell the difference in sound before or after the install. Like it so far.

A great system for the money

Built well, engineered to fit correctly. Thick tubing to prevent rust. Looks great. Only thing I would change is to use a quality band clamp instead of the normal exhaust u-bolt clamps.

Easy installation, although measurements on instructions were a little off. Nothing you can't figure out though. Installed this and the s&b intake, and am now getting 16 mpg, up from 14 with 36" tires. Not much difference in exhaust sound, but turbo really came alive. Throttle response and power have improved drastically. Very happy with purchase, and well worth the money.
