I have the PW muffler delete but with the factory air box its still quiet while driving around at normal road speeds. I'm still running the factory cat back exhaust so the car is still really quiet. I've only had two runs at the track using et streets and leaving the line pretty much off idle ( because paranoid about standard tail shaft) the car has run 11.7 at 122mph with a 2.0 60ft on united e85.

I think an 11.5 or 11.4 should be achievable with the standard fg turbo, air box and cat back exhaust on e85. Once I get my tailshaft sorted I will go to the track and give it a proper go.

Yeah will be good to see how it goes with the new shaft. I'm all for performance but if u can produce power and still look stock , then it's win win.

Someone went 11.3 with these bits and around 330-350rwkw depending on dyno.

Yeah I can't see much point in upgrading the exhaust or intake until I upgrade the turbo . If I'm going to make noise I want the car to at least back it up in performance.

Cool gives me something to aim for.

also is the restriction in the air box or the crossover?

I think glouva (user name) has run a high 9 with the factory cross over and aftermarket air box so I can't really see it being much of a restriction unless chasing the last few kw

Good to know. I will sacrifice some kw for a stock looking bay for the moment. Defects are not worth it these days

factory airbox and crossover netted me just over 400kw, that was exhaust GTX and cooler upgrade, valve springs, clutch,injectors and fuel system. went to aftermarket airbox when I went for E85 tune to push past 455kw
