There's no doubt that I like the sound of the F.I. exhaust, but the drone around 2-3k RPM is my biggest issue as a daily driver. It is loud enough to drown out music and phone conversations (handsfree). Outside of this range, the sound is phenomenal and nowhere near as loud even at 7,500 RPM.

In an effort to reduce the dB in the 2-3k RPM range, I will switch to the stock cats. Hopefully that's enough.


Im not sure maybe your car is different but i have no resonators and can carry a conversation in the car no problem.. even now with my non resonated test pipes i can carry a conversation in the car you just cant be flooring it and expect to carry a conversation need to know how to modulate the gas pedal. I talk to people on my built in bluetooth just fine as well..

Modulating is easy and fairly quiet while cruising at freeway speeds, but when the road slopes upward the droning sound gets pretty loud. In city streets, it gets too loud when I try to accelerate to 40mph. It is loud enough to rattle the interior.

What's really strange is that sometimes the exhaust sound is very civil and not even that loud even in the same rev range. For example, on the way to lunch the exhaust sounds really nice and smooth. I'm even able to listen to music while accelerating. On the way back, it gets very loud and sometimes raspy. My coworkers wonder about the same thing. I'm not sure why or how that happens.

EGT heat must be effecting it?

My exhaust on my tC in the morning is nice and loud, from the cold start. But later in the day after its warmed up, its back to the smooth purr.

ok sorry for the stupid question but on the F.I. website it only says their test pipes are "not legal for highway driven California cars." does this mean their legal over here in NC?

Not necessarily. ;)

I would bet that they are not legal.

I do know what the laws are from state to state. We are located in California so I put that disclaimer on there to cover us. Esecially due to the fact that I know they are not legal for highway use in California What you do with them once they are in your hands is not on us specifically if you are not in California.
