Default cobb OTS map with non-cobb parts

I'm planning to go stage 2 very soon. So I know the cobb AP has OTS maps but can I use it to flash the ECU if I'm using a Invidia downpipe instead of the cobb downpipe? I would think all downpipes are more or less the same (just a tube) so it shouldn't matter. I plan on using the cobb intake.

You should be fine as long as the intake and boost controller are correct. Keep an eye on AFR's.

You can certainly try, but prepare for boost issues.

What do the mapnotes say? Does it say "COBB DP" or, "any aftermarket CATted DP"?

CATless DP's are an issue typically regardless of brand, CATted are usually fine, but refer to the mapnotes for the OTS map you're thinking of.

The Cobb downpipe has 2.5in flanges restricting flow compared to you Invidia downpipe. The OTS stage 2 tune should run your car fine, but to optimise your performance I would suggest getting a pro-tune.
