i have been looking at exhaust system options lately, and i was wondering if anyone has opinions on this subject. i have been looking at the hks hipower exhaust, but i like the hks titanium racing exhaust better. the only thing with that is that the application is for 800-1000 horsepower. would anything happen if i put this exhaust on anyway?

 

they're the same exahust except for the Ti tip. 75mm piping and 120mm tip.

if u're going to be making that much power i hope u researched your other parts more than u have the catback hehe

 

lol...i had just the ragular hiper exhaust...it made a big difference..as far as the butt dyno goes..and i loved the way it sounded when i got on it...totaly awsome system. and prob the easist mod i ever had to do on her...man i miss her so..lol. good luck and have fun.

HKS Hiper is thermal coated so you shouldn't have any rust problems. I have had the Hiper on my last 2 cars (Integra, FD) and it made a big difference in performance. More than I figured any exhaust could ever do. It's easily noticeable. There is a HKS Ti in Japan that is a 4" turboback system and the Ti they offer on the USA website is just the Hiper with a Titanium tip. It's roughly $200-$300 more for the Ti thru most shops here... The Hiper is near silent with the stock cat and a 3"DP to other people outside the car. Inside it has a good tone that would make you think the exhaust is somewhat loud. Add a MP and that changes everything though! Gets obnoxiously loud.

 

so what you are trying to say is that the titanium racing exhaust and the hi-power/carbon ti exhaust are the same?

 

^^ No, the TI RACING exhaust is a complete TI exhaust while the hi-power and teh carbton ti exhaust are the exact same. THe only difference with the Carbon Ti and HI power is taht the canister on the carbon TI has a carbon fiber wrapping.

 

For the most part yes. The pipes on the Ti and Carbon Ti I don't believe are thermal coated... And the canisters are the same, just one is carbo wrapped with a Ti tip, The other has a Ti tp, and the original Hiper is just stainless. But otherwise the specs are all the same, weight may be a little different.

 

so if i got the HKS TITANIUM RACING EXHAUST, (where the application is for 800-1000 hp) and i didnt have, 800-1000 hp, would anything bad happen? example: on the normal piston engine floating a valve.

 

this thread is funny

 

no, just get the one you like.

 

I have the Carbon Ti. Sounds good but I think it's way too big. Came with the car when I bought it
