Fast Intentions exhaust is here!

Sibze

How much sound does the HFC's add? Same for the LTH's???

I have the 18 res right now

F.I. Inc.

The HFC's will increase the sound level 15%-20%

The LTH's will increase the sound level 25%-30%

Now keep in mind, this pertains to outside the car and with the exhaust that you have.

As far as inside the cabin, the LTH's will be quieter. You are scratching your head and saying how is that possible. I will tell you!

The headers have a higher exhaust note. It is more exotic sounding. The cats have a much lower note which is deeper. The deeper note tends to promote more interior noise resonance AKA drone. This is not to say that the high flow cats might have too much drone for you. Sound is subjective and everyone perceives it differently.

I am just stating what you asked, comparing one to the other.

Thanks, Tony
