What is the best I/H/E combo in terms of HP?

 

Injen/Xerd/SSR-Engineering 2.5" Exhaust with HKS carbon ti mufflers.

Just my opinion. You aren't going to see too much variation between setups. I would definitely get the Xerd long-tube headers though.

 

What kind of price and hp gain are we looking at?

 

search is your friend

 

Never hurts to have another thread...

 

yea i dont think another another thread would be bad... everyone has their opinion on different combos besides rite now there might be more members that have done these upgrades anyway that havent posted anything yet.

 

JWT/Crawford/HKS Hi-Power Ti

 

JWT+Crawford Plenium / Topspeed / Kinetix Test + HKS Hi-Power Ti.

Loud and powerful!

 

anyone have nismo CAI/motordyne plenum spacer/xerd headers/full fuji exhaust ? i am thinking of doing this during the winter... but i am weary about the system sounding to loud... i'm trying to get the most hp without taking exhaust note quality away, want it to sound like an exotic...

 

NUMBER1) The car is going to freakin scream with the xerd headers/race pipe/fuji exhaust.
NUMBER2)EXAMPLE: Would you rather have a convorsation on your first date with the hot blond. Or listen to the car instead? "I would pick the car instead" IMO
NUMBER3) If the answer to number 2 is you would rather here the blond babble. Then choose nismo parts.

 

i currently have a jwt pop charger with alphawerks headers, motordyne 1/4" spacer and a single hks ti exhaust w/ custom piping... sounds great... gonna dyno this weekend

 

borla headers = torque gains due to uneven piping
borla td = top end gains
helix test pipes
intake injen or jwt

 

Any idea on HP gain and price on any of these combos?

 

Xerd headers = ~15rwhp.
I also suggest a Crawford upper intake plenum. (10-15rwhp)
Injen intake...maybe 3rwhp?
Borla exhaust...about 6-10rwhp.
I also suggest doing KJR Performance pulley and lightweight flywheel (JUN).
