I'm getting ready to add a 3 inch downpipe myself as well as an e6 exhaust manifold, larger wastegate and a roller cam. I plan on getting an adjustable BCM so I can get more boost too. There are afew more mods I'm planning, but I'm gone take them one at a time so I can see what helped where. I'm guessing I'll have about 230-240rwhp when I'm through. That should be a big jump, especially when you consider all of those mods are only costing me around $200. There is a guy who owns a shop nearby with an SVO that is putting down over 350rwhp, he's just guessing until he gets it on a dyno, but he always underestimates instead of giving out numbers he can't back up. I've seen a time slip too, it was somewhere in the low 10's @127. These cars really make up there power at the upper range and his car has some serious mods to it. I don't want to go that far with mine....ok, I do, but I can't afford that many horses right now. Let us know how it goes.
