Wrong. 205 hp AT THE CRANK for the L36. Why are we STILL comparing apples to oranges like in every other thread you post in?

Oh really? I'd like to see your dyno sheet to prove the 25-30 horsepower please. I'll believe you when you provide one. And until you do. I am beyond calling Bullsh!t. No exhaust system is going to add anywhere NEAR 25 horsepower. Maybe if your running a stock downpipe and catback on a TURBOCHARGED CAR...but not your puny 3.1. In fact...you say they are rated 175 horsepower AT THE CRANK. Figure a typical 20% Drivetrain loss (175 x .20 = 35) so minus the 35 from 175 (175 - 35 = 140). I'd say your exhaust system MIGHT have yielded you FIVE to SEVEN horsepower. No way in hell it added 25. But...I'll let a dyno do the talking...I mean...if you want to prove your math and horsepower addition chart. By all means...go ahead.

Wrong. Beyond wrong. Go drive one. In fact...I have 3.29 gearing in my GTP...which is the same in the GT Grand Prix (If you didn't know...write that down in your notebook)...or SE for that matter (Wow...the 3.1 with a 3800 counterpart? No way)...and it is turning well around 2,500+ RPM's. So...nice try.
