from wut ive heard is
if theres anything wrong wit ur exhaust theres no warranty
this was from another thread so.
im not relaly sure!

 

Idont know where you been at man, but hte Fast Intentions produces like 10 WHP and 8 tq i think. Not sure what more proof you need but i got hte dyno sheet to back itup.

i also just got the HFCs installed and it made HUGE power gains. I think we at like 20WHP with FAst intentions HFC and Catback.

But if you just want sound and money is an issue what you got im sure sounds great!! CLips dude your killing us here lol.

 

haha, i thought you can dyi...noob so, its only going to have a deeper sound right, no civic crap? i probably go do it whenever i have the time. how long did it take them to remove it?

 

dyno, i doubt you can make 10 whp with a hfc..

 

sound clip plz

 

clippppp

 

dude!!! we want clips!!!!!!

 

Sound clips damnit!!

 

sound clips is the only way to go!! come on dude PLEASE!!!

 

this is what i've been asking THM for...a dyno of fast intentions catback vs. fast intentions catback + HFC

 

Sound Clips?

 

I'm so sorry guys. I will try and post up clips 2morrow. Haven't had time due to working non-stop. Yes I live in So-Cal. It took about a good 30mins to do. I kept my old resonators just in case I wanted to put it back on.

 

the fast intentiosn Dyno with jsut catback is on their site. we just got the HFC's installed yesterday. that dyno is coming to. Maybe next week though. i work 6-7 days a week so its hard to get out and about.

i know this though, HFC's will not make huge power using stock exhaust. but with a cat and HFC it will make over 20 WHP on most G37's. I can almost gurantee it. Look at their site for their dyno of just the catback. its there fellas.

ohh ps, i don't work for FI or any other performance compnay. I just do tons of research. I am almost positive i pay more monthly than 90% of forum users therefore i do 90% more research than most. FI is by far the best company out there but its ok if you like stillen. i got theri exhaust for sale currently.

 

How restrictive is the stock exhaust? I've never changed exhausts unless going FI, usually removal of cats do the trick as far as free flow for N/A goes.

Then again, it all depends on how ****ty the stock exhaust is to begin with.

I remember on the M3 all i did was remove the cats from the headers, intake and reflash. Most aftermarket exhaust no matter how expensive would end up showing no gain or less whp... point where the only gain was on shaving weight.

 

The pics and sound clips are up.
