Hfc w top speed and eBay y pipe soon I hope
 

Might pull the string on a pair of hfc to go with my top speed and eBay y pipe. I'll let you guys know what happens. Got a little more research to do

If they made by stillen or berk then your good. In your research, look into the motordyne art-pipes.

Was going to go CNT/ERZ Prob. Berk and Motordyne are WAAAAY Expensive

check out the z1 motorsports HFC as well.

haha ok cool. good to hear you do your research first!! Alot of people forget that portion of modifying a car.

IDK about those two, Ive been away from bolt ons for a while now but good luck your search wish I could be more helpful :tup:

Thanks. Yea I am going to check out the z1 motorsports ones as well. Think I might get my car re-dynod soon and if I am still stuck around 280 then I might wait being that the HFC wont yield anything close to 10whp

I have ART pipes, the ebay y-pipe and the topspeed exhaust with the resonated chamber thing between the two cans.

Pretty loud at WOT- sounds great after 4k. Little rasp from 3000-3800k. Looks awesome from the rear. Lot of hiss from 3000-1500k, but I don't personally mind that.

I want to hear this setup! This is exactly what I'm planning on too. Already installed CB now just looking for a decent y and cat combo

^^^ Just grab any y-pipe. When you add it, the sound will double. I cant imagine the increase I am going to get once I get rid of the stock cats
