Guys I was thinking....Would you consider Jet Hot Long Tubes, 3" Y-pipe with no cats, and an SLP Loudmouth 1 to be a restrictive exhaust the a car with the bellow mods? I am looking for some missing rwhp/rwtq on my car and aside from tuning im wondering if my exhaust/y-pipe is the issue..the headers i know are fine, and im not going to a 1 7/8" long tube...What exhaust do you all recommend for a 383 and what gains on the dyno do you think ill be able to see by letting her breathe more?
