So i don't plan on doing any FI when i get a G35 just the basic airflow (intake headers full exhaust)... Ive been searching around for the HKS exhaust system and found these....can anyone tell me what the power difference is between these HKS exhausts and and why? what are your opinions

HKS HI Power dual exhaust

HKS Legamax dual exhaust

For starters, the Legamax has 65mm piping while the HiPower has 60mm. The picture of the Legamax in that link is not accurate. The Legamax for our cars has oval tips. The Legamax is rare on this forum. I'd say 95%+ of all HKS coupe exhausts on this forum are HiPower.

Here is the Legamax sound clip.

Here is what the Legamax really looks like.

 

Edit: Whoops nevermind I dont know what im talking about.

 

By other I assume you mean the Legamax. The Legamax is not an axleback or muffler. It is a y-pipe back, so it includes both the midpipe and axleback/muffler.

HiPower
catback
true dual
60mm piping

Legamax
y-pipe back (include midpipe and muffler)
single (dual exit, just like stock)
65mm piping

 

Ninja edit, lol.

 

thanks for clearing that up man!
I have another question while we are talking exhausts.... So sense im not gunna be upgrading that hell out of the G do you think a HKS hi power would be over kill? could i just buy some nice headers y-pipe and exhaust with about the same output of power? if so what would you recommend?
Really appreciate any feedback!

 

HKS hi-power was my first mod!!! besides clear corners... id say get some nice headers, high flow cats, and the HKS and tune the B!TCH! the VQ will produce roughly +10 hp using the hi-power alone.

 

The HKS alone is great. Nice 'lil top end and a seck-see sound.

 

HKS HI POWER FTMFW!
definetly felt more high end power

 

You put your HKS on already? You like it I'm assuming?

 

yessir! this is by far the best exhaust system i purchased

im just dreading the fact that its 1500 bucks lol

 

One word: used

I bought mind for $800. They go for $800-$1000 used.

 

look up member TIAN
i believe hes selling his used HKS for $900+ shipping

i bought mine used to and it was expensive but well worth it!

 

that says a lot coming from you
