Is $170 a deal for macs?
LOOK IN THE EXHAUST FAQ for a dyno'd comparison between Mac mids and LTs. THERE IS A 5-8RWHP DIFFERENCE under the curve, almost nothing on the top end.
Christ, since you're all too lazy to read it, I'll post it for you :
.22 and 1.5 MPH was the gain swapping Macs/Mac 2.5" ORY-> Grotts and 3" Y pipe at the track.
PLEASE STOP TELLING PEOPLE MIDS ARE NOT MUCH BETTER THAN STOCK MANIFOLDS.
I never type in caps, but this kind of thing really irks me - people read here like it's the gospel truth so please do your part to make sure they are educated with the correct info !
I personally made 410rwhp/415rwtq through Mac Mids, Carsound cats, LS1 intake and a baby 222/224:114 cam with 5.3L heads.

Also have another question, if I get longtubes and do not do the provision and egr thing and the light comes on. Will a basic tune or the OBDII test will able to cancel out the SES light? Cause I know when the SES light is on, isn't that a automatic fail in the smog test?
