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.

Sent Wrong Part at first but fixed it.

Reviewed By Lance L (Charlotte, NC) Reviewed for a 2015 Ford Explorer —2/4/2016 5:29 AM

They sent me the correct sku number but it had TWO Drivers Side Mufflers and not one driver and one passenger. They sent me another system with the correct parts inside and I shipped the one wrong one back. They need to do a better job of QC on their assembly line to keep things like this from happening. It delayed my installation by a week. That I was not happy about. Once installed, product runs great.
