We put the cobalt on the dyno after installing our 3" catless downpipe and did some testing. it resulted in 255whp compared to our stock baseline of 240whp

Did you guys tune after installing the downpipe and also what other mods are there if any?
Thanks

@brv49 that percentage is lost in the drivetrain...parasitic loss.

GM lst the cars as 260/260 (crank HP) but most cobalt's seem to dyno in the 235-240 WHP range w/ 245-255 W torque.
GM understated its peformance numbers honestly imo. My friends RL stock only dyno'd @ 224 WHP and 253 WHP w/ GM Tune.

nice numbers. 15whp for just the downpipe is not bad at all. maybe with an intake and exhaust too will bring you to 270whp or more.
btw, nice ss/tc bro. =)
