Anyone that has an STS, I wrapped my exhaust from the collectors back and there was a noticable spool time gain and it seems that i gained power so, if u wanna lose some of that lag, do as they say and wrap it...

Bummer I was hoping to finally see a before and after dyno sheet. It would be nice to actually see the differance. Glad it worked out for you.

i calculated like around a 135rwhp gain or so when i did my STS kit. all i had when i was N/A was, flowtech LT, ORY, corsa catback, ASP pulley, and lid. and my first dyno on 7.5psi was 472/501ft-lbs. now i make 503 with the new addition of a cam, springs and less boost

I was referring to a before wrapping and after wrapping dyno sheet. I know I felt a seat of the pants differance when I did mine but I've still to see the actual numbers or rpm gain in boost differance that one benefits posted.
