I can't decide whats better GTM Resonated Test Pipes or Berk HFCs. Both seem very popular.

I have Tanabe axle back exhaust, 2.5" custom mid pipe and 2.5" exhaust depot Y Pipe.

As far as build quality and power. Both probably close.

I want to know which one produces less rasp?

Thanks!

 

I believe HFC would produce less rasp

 

So I've heard lot of videos with Test pipes. Even Resonated ones sound raspy and also smell. So I'm leaning towards HFC's for sure.

Looking at either Berk or FI HFC's. Is it worth going with Resonated ones?

Thanks

 

Instead of posting up multiple threads, and PMing guys asking "which to get", please do your research and take the time to search. There are hundreds of reviews on this forum, and if you utilize it correctly, you will find every single answer to almost any question you can think of.

Is FI HFCs/RHFCs worth the price? All I'll say is, you won't find a customer out there that regrets purchasing them.
