help me out here 7 lovers...
 

i'm looking to get a dp and presilencer (2.5") from racing beat, but before i do, i wanted to know how much power gain will this mod give me?
i know racing beat claims 14% for an '87 t2, but for those of you who have this set up, is this worth $239?

p.s. i have a '91 t2 jspec engine in an '87 chassis
only mods are cai & turboxs hp boost controller...also an a/f gauge and a boost gauge

Yes, it will give you great gains. If I had a TII, I would buy it only from RB. RB has been building RX-7 parts for over 20 years, and are the only tuner in north america that is RX-7 and Miata sanctioned by Mazda. I would trust ANYTHING Racing Beat says as law.

Yeah go with RB.....like Rico said they have been around the longest.....plus from what ive noticed a lot of tuners get their stuff from RB then add their mark up to it....

Exhaust mods are ALWAYS worth it on a turbo FC...
