Nope. Over 100miles now with no CEL. The slight rasp I had in the beginning is now only present when cold. After 5-10 minutes of driving and warming up it completely disappears. Drone is exactly the same as with my Stillen cat-back only. The car feels much lighter and easier to accelerate in any gear. It's definitely faster and more powerful than before. This is probably the best mod I've done so far. VERY happy!

Any sound clips?

which exhaust you have

Q8y_drifter

Stillen cat back. I have an HR sedan.

J2S2M, No i don't. I figured since I have an exhaust + intake already a sound clip is pointless.

nice , set up

So I'm reporting here after driving 3,000miles. first of all, no CEL at all. 2nd of all, there is no rasp whatsoever, just a straight up mean sounding exhaust! In terms of loudness under normal driving, my setup is now a hair louder than with just my Stillen CBE. It has become MUCH quieter over the last 3,000miles during normal low RPM driving but really opens up when you go WOT.

I'm going to get an in-car sound clip within a couple days (maybe even today If I can)

Here's a sound clip from a dyno and a before/after comparison of the whp gains >>

Previous Dyno Run
Mods: Stillen CBE and Injen CAI, No TUNE
Numbers: 252.7whp

New Dyno Run
Mods: Stillen CBE, Injen CAI and Invidia HFC, No TUNE
Numbers: 259.7whp

So average 7whp gain from the HFC
