MOD Questions...

I have a 06 STi and I have a SPT exhaust on it now with a Helix V3 DP. Is it worth it/ will i see that much of a power gain by changing the exhaust? I was thinking GReddy Ti-C exhaust with the Helix V3 Downpipe...

I was also wondering where else to start on mods. I have the SPT exhaust and intake, the Helix V3 DP and the cobb accessport stage 2 and a walbro 255 fuel pump. Whats next?

Well, on my 06, I had more money into the handling of my car than into the straighline speed but, Turbo XS catless stage 2 and K&N panel drop in is where it was for me. The intakes I tried were always downgrades IMO.

If you want speed and daily drive-ability, you could go w/ a modest 18g. Then again, I forget, does the 06 AP have a map for the 20g or was it 18g? It's been a while.

I don't think switching the cat-back will gain you much power, if any.. just a different sound. And yes, pro-tune if you haven't yet.
