GM Supercharged 3.8 Question

Had a little tap tap this morning when I started it up (actually, it was pretty loud)…went away after 5 minutes of easy driving. It sounded like a lifter…is this common on these? The car drove/sounded fine after warming up. I’m thinking I’ll change the oil (maybe the dealership put to heavy of a weight oil in)?

Also- I’m assuming downpipes are the exact same for GPs and Regals? ZZperformance has some awesome prices on downpipes listed for GTPs…maybe I will get one. I need some better front brake pads and rotors first though.

Tap is NOT common.
DP’s are same. I have found that most of the performance parts are reasonable if not cheap for this drivetrain.

Not to rain on anyones turbo parade but there’s plenty of m90 setups running the same times and -100whp as the bulk of the turbo setups. you can’t beat the top end of a turbo but you won’t beat the low end of a blower…it’s a trade off, there’s no way you can declare one better than the other

I understand what you are saying and there is truth in the statement.
