Can't speak for their tps, but the M2 rear lower brace didn't fit my Z. They gave me a full refund even after a few months.

 

Yup. I dynoed at FT's dyno days 2 years in a row. The first year without TP's I put down 245whp then the next year with TP I dynoed 257whp. No tuning at all. I also went from trapping a best of 101 on stock cats to trapping as high as 105 after the test pipes.

 

Hey Clay. What about these off of Ebay. I'm thinking about getting them. http://cgi.ebay.com/ebaymotors/MEGAN...Q5fCarQ5fParts
