Looking to make my exhaust a little louder but don't want to mess with the whole thing since i'm pretty happy with the tone. I've just got a muffler delete but I thought if I got a set of hfc's that it would improve the sound a bit. What do you guys think?

 

High flow cat will make it louder if your already happy with muffler delete you may benefit from it

 

Yes it will make it louder. It actually got a bit too loud for me when I installed test pipes. I get more drone now and cold starts are very loud. I have a full exhaust.

 

Seems like, from what I've seen, HFCs will amplify your existing exhaust note while potentially adding some rasp.

Resonated FI HFC's seem to be the best bet, but of course they're the most expensive.

 

Are you running stock mid and y-pipe now? If so then maybe try increasing the exhaust tone by switching to a larger diameter pipe ( stock to 2 3/4 or 3").

 

I got z1 intake/hfc, top speed y pipe and y pipe back exhaust. I love the sound, not to loud on inside. Outside is pretty loud but in good way 😍
Cold start is louder then goes down to idle and sounds stock

 

Could you make a video? I have my TopSpeed exhaust on the way and I'd like to pair it up with HFC.

 

Depends on the HFC that you get. I got FI RHFC and they had no drone or rasp at all.

 

I have fast intentions NON-resonated high flow cats with fast intentions catback exhaust with 18" resonators and have 0 rasp.

 

We have the Berk HFC in stock as well as the Motordyne ART Pipes
