Better than stock

Reviewed By Jason H (Carrollton, TX) Reviewed for a 1988 Mercury Grand Marquis —6/9/2009 8:42 PM

But not high flow. They allow a little better flow than the original converters, but not much more. They do sound better though. If I can get true duals on my car, they may work even better and the y pipe may be the main issue I'm having. Installation was a cake walk. Getting the old ones off was a pain, but these went on very easily. Would have been better if they matched up to the OE air injection without modification, but that's not a big deal.

2016 Infiniti Q50S Red Sport

Reviewed By Farzad F (San Diego, CA) Reviewed for a 2016 Infiniti Q50 —12/6/2016 7:07 AM

This is a great system with a noticeable power gain! It did have a small issue where the V-pipe hits the frame on the driver side. Had to hammer and bent the pipe to open up more room. Nothing crazy but it needed about half an inch more gap. Everything thing else os great. It does work perfect with the 3.0L twin turbo engines as well.
