Decat and which exhaust?

Ok. Novelty of decat with straight through powertec cans producing obscene amounts of noise has now passed. And the thought of 10 days in the Alps with this noise constant is terrifying.

So what would people recommend?

Tbh cats with the powertec was about right! But I wanna keep the decats as I hear they are better for chassis and reliability in general.

Decat half half sleeve powertec sound good?

Popped my stock cans back on which i would say are about 1/4 or maybe 1/2 (so lets say 1/3rd) sleeved as they are degrading.

MUCH MUCH quieter. Too quiet. Its now more quiet than cats with powertech. Still some pops but really muted. It does now let off awesome shift farts like a gun though.

So i think a powertech somewhere between their quiet can (assuming would be similar to half sleeved stock can) and their loud can would be best.

going to order some 150mm perf PT's i think. Their quiet can is 300mm so hopefully 150mm will be somewhere between my stock 1/3rd sleeved and straight PT's.
