I would say 20 at most. Its just a catback maybe good for a couple more than any other because there is no muffler.

MY LOUD MOUTH DID NOTHING FOR ME PERFORMANCE WISE. BUT THE SOUND WAS PHAT COMPAIRED TO STOCK SS CAT BACK. SINCE I HAD A 4.10 GEAR INSTALLED MY CAR SITS ON THE 1800-2100 RPM DRONE AT HIGHWAY SPEEDS IN SIXTH GEAR.IT SUCKS VERY BAD WHEN DRIVING WITH THE WINDOWS UP!!!!!! ALONG WITH THE WHINE OF THE 4.10, I DONT EVEN NEED A RADIO! HA HA HA HA

HEY I JUST MADE MATTERS WORSE! I BOUGHT 1 3/4" HOOKER LONG TUBES WITH AN OFF ROAD Y PIPE. ANY ONE GOT ANY INSTALL TRICKS/TECHS? I'M THINKING OF JUST PAYING SOME ONE TO DO THE INSTALL <img border="0" alt="[bang head]" title="" src="graemlins/gr_banghead.gif" />

The LM on a SS or WS6 wont give u that much. On the other hand on a Z28 or a T/A u will see 10-15rwhp increase. I gained 33rwhp and 22rwtq with only a LM and Lid over stock. The car went from 292rwhp 314rwtq stock to 325rwhp 336rwtq. So for sure i gained alot from the LM but dont know the exact number since i did the LM and LID together. I hope this helps.
