991 gt3 exhaust bypass center or sides and valve control?
 

14 gt3

would like to.........
-remove as much weight as possible
-retain as tame as possible "quiet mode" for pulling out of parking garage
-much louder when open but not straight piped obnoxious, like a gsxr 1000 with a relatively quiet full system with DB killer inserted if your familiar
-ideally a higher pitched scream instead of a deeper base/big bore/

not sure if side muffler delete or center and soul/fabspeed/custom muffler shop..
Does porsche give people trouble for drivetrain warranty claims with these?


thanks

thanks

I had the same question as you not that long ago!

You have to call G from GEXHAUST, when I called him he gave me all the answers I was looking for, he explained everything and he seriously hooked me UP!

Highly recommend, just call, trust me:
