I had an 04 STi with a bunch of APS stuff on it. SR55, DR725 etc... I was wondering if any of you are using the APS turbo/exhaust manifold or inlet manifold and if so what type of gains did you get? Any input would greatly appreciated. Thanks in advance.

 

Sorry not aware of anyone using APS stuff on their evo.

 

I've been looking at it as I liked their suby stuff and rexes went well off the mods but I think I might stay away from them until I find out more as they only started testing on an American evo 8 last year and there evo 6 stuff wasn't that good..

My 2 cents

 

Yeah, giant of the evolutionoz site is using their 3.5 inch exhaust and CAI. He seems really happy with 192 atw (or so I recall) without a tune on his 9.

 

I have there dual port BOV I love it no stall issues at all.
