Fast Intentions TDX Catback Exhaust Install Review with PICS!!

F.I. Inc.

O.K. here is my thoughts. Now, this specific car has:

Stillen Gen III intakes
Fast Intentions High Flow Cats
Fast Intentions TDX Cat Back Exhaust

Keep in mind, it is also a 7AT (Automatic Transmission)= A slightly higher percentage of drive train loss.

Now, I am the manufacture of the exhaust and I can tell you there is no way this car picked up 50 RWH (Rear Wheel Horsepower). Don't get me wrong, I wish this was the case but it is not. I think what happened was the car was originally dynoed in a lower gear 3rd or 4th for the baseline by accident. Now, from the number of roughly 306 which looks very accurate I know the car was dynoed in a 1:1 gear for the after session. The car showed very low numbers stock and this is what leads me to believe this about the gears.

Now, the cat back exhaust proven to make over 20 RWH and the HFC's are good for another 5-6 up top but the HFC's show their biggest contribution down low and in the mid range. As for the intakes well I would be satisfied if I saw 8-10 RWH from them! Now add this all up and you end up with 32-36 RWH on the high side. Lets be conservative and say these three mods compounded together will give you 28 RWH. Pretty respectable in my book. Now with all of this said, the number I just posted above will be slightly lower on the Automatics over the manual transmission.

This car dynoed in the correct gear should show a baseline of 268-280 RWH and once these mods are on we are seeing around 305-315. If anyone has any questions about what our exhaust actually dynos, just check out this link:
