I had my car dynoed Friday, it has 1200 miles on it...
Stock- 357.5hp- 362.7 tq
JDM filter- 376.3 hp- 364.7 tq
FRPP catback (not the fr500) -390.8 hp- 373.7 tq
This was done on a dynojet in 4th gear, my car is YDH1 car. Do these numbers sound about right for my mods? I kinda of think I should have went with another brand catback. It only made 14 extra hp and its too loud for me. What do you guys think? I dont have anyway to post the dyno sheet yet. Thanks

I too, put up a 360rwhp on the dyno jet stock. I also run the JDM CAI which I est. around where you are. As for the FRPP exhaust, while I am not very familure it sounds about right. People post a lot of good things about Bassani or Magnaflow. RWHP gains from 18 to 24. I myself run Mac. While they are not SS, dyno tests revealed the most power. Did you do an "X" or some sort of low restrictive "H" with or without cat's?

those numbers are right for the mods you have. I think with an xpipe you could have 400hp.

I think that your numbers are right on target but even a bit on the high side. Looks like you got a strong one and that's great.

Congrats on the car and welcome to the site, Julio.
