Whats the HP difference? I'm buying an HKS DP for $120. Do you guys think it's worth it or should I save up for a DP w/ a bellmouth? Thank for you inputs.

If u are going to get larger turbo later... get bellmouth design DP! If u are not... then stay with HKS DP is good for your car! i current have it on my car!!!

 

Thanks, I think I'll stick with the HKS for now. I dont plan on getting a larger turbo for awhile

 

With a bellmouth downpipe you will gain 8 hp peak and 15 hp max lower on the hp curve over a flat-flange design like the HKS. This is from the current issue of Sport Compact Car which tested the SuperSprint turboback exhaust (flat-flange) against the Vishnu (bellmouth). This is with STOCK turbo. The bellmouth to me is definitely worth the extra money. Shiv usually does his tuning correctly the first time and doesn't offer a product that doesn't produce.
