Who was doing this upgrade in Atlanta? Also, have you seen any gains with the exhaust flow?

Thanks!

Are you referring to Doug's (Four Door's) WMS downpipes?

I haven't installed anything yet.

I'll be going from Piggies to the WMS Widemouth DP's and expect to see 5-10hp over the Piggies in the higher RPM's. I'm still on the fence with installing dump pipes.

I really need to ecux log the car before i make the changes (DPs, LWFW, and stage IV clutch), but i don't have the equipment to do so.

but at 24 PSI there has to a difference over stock diameter pipes. The highflow cats are also going to contribute to better flow.

I'm still expecting 5-10 HP from about 6000-7000 RPM where its really moving some air.

however, on K03s, we don't flow enough to matter. you know, the "other" people...

but by then i'll have another car which will allow me the time to make some downpipes.
