MBRP makes a quality downpipe. I had to get a portapower to push the floor pan over enough to allow the downpipe to go between it and the bellhousing but it worked out nicely. I can hear the turbo spooling up and now that the catalytic converter is gone, I get better fuel mileage. The engine seems to be quieter now, also.
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.
