i was thinking to go with stillen but i had their race pipe on my G35 with HKS exhaust and the sound was just rediculas so i'm kinds leaning on something else

 

To be honest, I think they all use the same CAT so the sound should be the same between them all. Personally, I would go for which ever one of them gives you the best price and has at least decent customer service. You don't want to buy a product that doesn't have customer service behind it.

 

so what kind of gains did you get with Berk HFC

 

Here you go!

K thanks and also do you know if the chek engine light comes on or no thanks again

 

Not with HFCs it doesn't.

 

Fast Intentions all the way

mike

 

K thanks guys im gonna make a new tread and put up some pix of the G with the exhaust on

 

which hfc produces more power? or are they all equal

 

I guess they all pretty much equal the diff cant be more than 1or 2 hp

 

i would do fast intentions

 

Go with fast Intentions. I love them. You won't be sorry.

 

I went with BERK, top notch all the way from customer service to quality of packaging with the shipment and most importantly the excellent product. After my experience with the quality of BERK's product, don't for an instant think that the lower price equals an inferior product, you'd be absolutely incorrect. >>> MORE DETAILS <<<
