For the love of everything Holy... I've NEVER seen a dyno(Before and After) for this exhausts...Does ANYONE have one they can post?

I've looked at every post I can find, and cannot find ANYTHING, not even one for AFTER the install...

 

that and the invidia v4 exhaust!!! i always wondered, b/c i was stuck between these exhaust systems and i wanted to buy for the sound and power but since no one had proof. i had to go for sound.

 

I know how you feel. I've been trying to research these exhausts for a couple months(mainly because I didnt have the money until recently) and can't find a dyno anywhere to actually see if HKS loses power or how much greddy adds(if any)

 

I've got dyno plots with my HKS exhaust, nothing from before though.

Can't contribute it all to the exhaust, but I was the highest N/A AP1 there.

 

Same here
My Ap2 did 238 WHP (or so)
the only Mods are
HKS Exhaust
Skunk2 Test Pipe
and
K&N Drop in Air Filter

Dyno day at JDM

HKS FTW
Not too loud
Not too quiet
Just Perfect

 

i would suspect that the majority of your horsepower came from that test pipe.

 

I figure 10 from the TP, 5 or so from the HKS and then another 5 from the filter therefore no powerloss
My 2 cents

Greddy single makes good power, there's a HKS vs Greddy thread

 

I've read this thread, though I'm wanting BEFORE AND AFTER dynos. this thread(from what I've seen, correct me if I'm wrong) does not contain this. Thank you for not reading the original post.

 

Obviously you didn't read this:
