Yeah not expecting anything massive. This was more of a safety thing, but also reap the whatever the performance gains are. The cat in the OEM MY01 up-pipe is small but restrictive. Expecting some earlier spool with the EBCS and a tune.

Another reason I chose the Grimmspeed pipe as it has the following ID specifications: 1.865" ID @ the header end, 1.755 at the turbo end.

This is conducive to velocity and thus spool (in theory, anyway.)

If you were to believe anything from MRT, I doubt there would be 20awkw in it!! Maybe from stock untuned, going to tuned. Hard to understand the context of those comments.
