CAR:

2006 WRX TR
Mods: Hi-power HKS catback, AP stage 1.

I just bought a Invidia DP (V3 catted), coming this sat!!

anybody experience an HKS cat/back mate with Invidia downpipe (catted)?

Hows does it sound? how loud?
Hows the power gain?
problem installing it?

any suggestion? thanks guys!

 

i gotta hks carbon ti (samething basically) and a helix dp... its pretty loud, not as gurgly as the helix exhaust, but youll be a happy camper....and DEFINATELY not as loud as the magneflow, dang that thing is loud

 

wat year is your car? wat other mods you have?

 

anybody else got an invidia catted downpipe?

 

05 wrx

my power mods thus far:
hks up pipe
helix down pipe
hks carbon ti
vishnu xede - dyno tuned
intake resonator delete
apex'i grounding kit

when i can source a cobb AP i will be upgrading to the vf34

 

so does the hks hi-power work well with all 3 inch downpipes?

 

I don't see why it wouldn't.
