If the car is stock except for Berk.. its quiet. On a scale of 1-10.. its a 3/4.



Paired with ART test pipes, or HFCs is a little different story.

But coming from someone with short tails, BERK is weak lol.

The big questions is, will resonated test pipes lower the hiss? The drone would be a bonus but not the major issue.

Thanks for all the great feedback everyone.

For whatever it's worth, my ART Pipes connected to CNT catback had hiss. I like the sound, so it wasn't a big deal.

However, there was zero rasp and drone was only in the lower 2k range when lugging the engine (medium+ throttle under too low of a gear)

I have the F.I. resonated TP's and the F.I. 18" CBE. The hiss is definitely there just like you described it. When letting off the gas it hisses till just under 2000 RPM. TP's will not get rid of the hiss. Doesn't really bother me anymore since ive gotten used to it, and with the radio on at all i dont hear it, just the nice low growl from the F.I. setup. More than likely the TP's will make it worse then it is now.

FI non resonated and ART pipes major hiss and rasp on decel

Seems like j bends or those 90* pipes off of some part of the CBE are in your future.

Edit, branch resonators

did it sound good though otherwise? any videos?

I mean it is deep and loud. No sound clips yet and they don't do justice.

would you buy again or go with 12" res? i'm hoping it'll sound awesome. lol freeway drone doesn't give you a headache? dont have to yell over it?
