im looking to get either test pipes or HFC for my stock exhaust on my 04 coupe. which do you think is better (power wise and sound wise)?

 

Better? Better for what?

Powerwise, test pipes flow better.

Sound, that's subjective.

Can you deal with excessive exhaust fumes, rasp [stock exhaust tends to rasp even with resonated TP], and a louder exhaust? If so, get test pipes.

 

Do you guys have emission tests in NJ? If so, you may want to consider HFCs

I have Berks and have used them with the HR Y pipe and stock exhaust and loved the sound.

Everywhere I went I got complements. Then I upgraded to Fast Intentions Intimidator catback exhaust and the party continues.

I still have my stock exhaust and may switch back for sound purposes but all in all, you won't regret it if you went with HFCs.

For one, I don't have a CEL.
2. My car don't stink
3. I passed emissions in under 30 seconds when I went (6/25/09)

There you go!

 

I'm in the same dilemaa. Ive heard videos of HFCs on a stock exhaust and it doesnt sound much different to me. I want a loud mean-sounding exhaust. I don't really mind te smell as long as you can smell it driving. What do you guys think? Whats the best place to buy RTPs? FI?

Sorry didnt mean to jack your thread.

 

wuts the best brand for hfc? crawford,kinetix,Fi, or berks?
