exhaust for s13 rb25det swap

[IdrifterX]

i want a hks high power exhaust what type of performance header and catalytic converter should i use that would go well with an rb25

[Joe]

tubro engines dont use a "header" in the typical sense. so none. and any good clean cat. doesnt matter the size or brand. 1-2hp is the max youll gain from a clean stock one to a "high flow"

true so what type of down pipe should i use to match w/e cause im trying to get an idea of the perfect exhaust for it with a hks hi power

[Joe]

one that fits?

lol there isnt some magic combination thats gonna all of a sudden give you another 20hp.

If your using a stock turbo, look into modifying an SR20 down-pipe. (cut, rotate, and re-weld flange) If not stock - it all depends on the turbo you have.

Seriously man, think! (This is why I could never be a Mod...)

I could be wrong but I dont see the real benefit of installing a dp and downpipe elbow. You might get what 2-3 whp??? But then again im upgrading the turbo and manifold soon.

Order some 3" SS bends, 4ft SS strait, turbo flange, and cat flange. Then cut to fit and weld. Its really the cheapest/easiest way. Welding skill is a must with motor swaps.
