I do not know what should i go with. I am getting the HKS hi power exaust. Also will it be a difference in sound between the two. I am trying to stay as silent as possible

 

If you are trying to stay as silent as possible then get HFCs. TPs will be louder and may have rasp when compared to HFCs.

Hopefully the HKS won't be too loud for you, it will be louder than stock.

^ lots of club people here have the HKS, so there will be no issue to how they sound :P


So bye bye Y Pipe? lol at least wont be hard to sell

 

If your concern is keeping it as quiet as possible, get the inner muffler silencers.I have Test pipes on mine and the attenuate the sound to a decent tolerable level, definitely not as loud.. . I think you get the raspy sound with or without the test pipes. What I don't like is the fumes you get in the cabin when you come to a stop and the windows are down..

 

^ or when your behind that person with the AC on

 

resonated test pipes arent much louder than hfcs. casually driving, test pipes and hks arent too much louder than stock. its not until im over 3000 that it starts getting loud (though im biased coming from an injen ses). try going through youtube listening to clips or wait til we're together again and gauge the loudness, though i think everyone is pretty much using non-resonated pipes.

 

Why do you want it so quiet? if you want very quiet HKS is probably not for you.

 

I agree. The I personally have the Stillen Tru Dual, and its literally stock sound.

 

so i will not get the fumes with HFCs??

 

I just heard that test pipes would be more loud and raspy compared to HFCs. I am focusing on gains. so the question is will gain more power with the test pipes or HFCs? Thanks for all the replies.

 

Test pipes FTW! I got test pipes n HKS.. Sounds low casually driving but when im at WOT its loud

 

test pipes will gain more hp, but will be louder, raspier and produce fumes. you can get resonated ones but I'm not sure if they gain more hp than a HFC

 

test pipes are going to flow better than a cat. i still have a set of these still in their box:

Get the HFC's then you won't have any rasp or fumes. HFC's still offer a gain in HP and well worth the $!

^exactly. if you dont care about the rest, test pipes will give you the biggest gains.
