I'd say around a 20hp gain at the wheels with those mods. Springs dyno'd his car after he installed the TOG's and showed a 19hp gain at the wheels. I do not recall if he had a custom exhaust or intake. I'm thinking he did though.

So your saying that just adding the headers gave him close to 20 at the wheels. This doesnt include the 4-5 should expect from adding the CAI and slp exhaust does it.
