My 04 STi was heavily modified with all the APS stuff available. The big parts were the SR55, DR725 and 3' tbe.

I know they make a few pieces for the EVO but I haven't heard of anyone using their
high output exhaust manifold with ball bearing turbo and high output inlet manifold.
Are the Japanese parts more efficient at creating more hp with the same stuff? I just got a 9 last week and won't go down the modding path I did with my STi. I am just curious if anyone here are using the parts listed above.

My neighbor had the APS cai on his 03 and loved it, and from what I have read so far, I guess their BOV is also liked.

Thanks in advance for info or links to EVO's using the APS stuff. Happy holidays!

 

I will be buying a APS 3.5" TBE for $1100 it's not the cheapest, but the backpressure is only .5 psi and will ensure minimum HP loss while I attempt to hit my 700awhp goal in spring.

 

Its a nice exhaust but LOUD!!!!!!!!!!!!

 

I have their 3.5" TBE, their intake, and their FMIC. I really like all of their products. They fit very well, and my car dyno'd 225 awhp stock, then 275 awhp with just intake, exhaust & mbc that was only bumped up like 1 psi. It was 265 with the tip in and 275 w/ it out, and yeah it's not exactly a quiet exhaust but it sounds pretty good.

 

I have the 3.5 tbe, bov and fmic also was going to buy their turbo but they have not released it yet. My subie was all APS too.... Love the product and quality.
