So again my aim is at least 300WHP, there are a couple of exhausts that im interested, included in my set up I will run a HFC.
Which is the best choice, for gains as well as sound (i like quiet!!) and low drone.
Stock with HFC
Greddy TI-C Single (70mm) with HFC
THE NEW HKS Hi-Power Ti tip (75mm) I like the way this looks A LOT!
help me out fellas

 

ive got a greddy kit w/ the hks dual hi-pwr setup with no complaints w/ factory cat...great sound, especialy when just cruising...i've been thinking abot getting the 3" greddy single Ti-C w/Berk high flow cat though...if interested may consider selling my hks....

 

Stock w/ test pipe can make 300WHP with a good tune at app 10PSI

 

ok so lets say i get a great tune and hit 300whp with stock exhaust and test pipe... what numbers would be possible with a HFC and Greddy/HKS single? I mean if it will increase it to 320WHP its worth the investment

 

320whp is near maxxed out on that turbo. it will be a hot air blower

 

is it even worth buying an exhaust for the greddy kit, i don't want to spend $600 for 5WHP

 

I had a hks on my car for my first tune and I made 245/190 on 10psi at a very good shop who knows alot about tuning ems on s2000's. My map was rich to make it safe and conservative.

I had a couple exhaust leaks that didn't get fixed until a day later. That hurt my numbers and I think the turbo is going out.

I bought a TiC single and got retuned and made 275/220 at the same boost. Either exhaust leaks are worth 30hp or a better flowing exhaust is?

Sell the hks and get a TiC

 

i would worry about installing the kit first with a MBC and hitting 10psi and getting that tuned.

see where your at after that. the highest hp i have seen with that kit was 317 dyno dynamics uncorrected and that was 10-12psi with water meth.

 

you know im talking about the NEW HKS hi power single right? the 75mm.

 

oh, well buy that. i wish it was out when i got my tic
