I have a 2000 b18b. I've heard from reliable sources that a 2000 USDM ITR exhaust manifold bolts right up, and offers pleasant gains in HP. I was just wondering if any of you have done this...

I'm almost getting it for free so dont bother trying to steer me elsewhere..THANKS!

 

Yes it will bolt up, you'll get a little bit more power, but not much.

 

it's best for you to get the ITR manifold and the ITR exhuast at the same time, so you can expect more of a noticeable performance gain.

 

thanks...i already have apex dunk piping for a 94-99 GSR coupe application bolted to a pre dynomax ultra flo....pretty much a comptech or dc setup (they use ultra flo....shhhhh)

i originally had a tenzo intake that i got for free, and then i got a generic one that fit better (filter wasnt so close to abs lines), and then now, i traded that second intake and some other stuff for a AEM cold air with bypass valve (i dont use it...even if it rains)

 

h:

 

So how much more power would an LS owner expect from this mod`..?

Also, would it bolt on directly to a 98' LS?
