It sounds great. Definitely better then it did with the OEM ypipe with HFCs....deeper but at the same time it has a higher pitch race tone when under full throttle. It also reduced the rasp quite a bit.
The construction of the y-pipe is great, fitment it perfect, sounds great, but almost Zero performance gain in comparision to the OEM yipe. I did a 3 base dynos with OEM exhaust, then 3 dynos with the HFC's 2 hrs later (11hp & tq gain across the power band, then 3 dynos an hr later with the Tanabe Y-pipe. I got almost 0 gains from the y-pipe but didn't lose power anywhere either...basically 1-2hp midrange.
I'll take the car back to the dyno again down the road to see if I get more gains, since I only did 3 pulls for each setup.
