Alright guys I need a answer on something. I bought the Blitz Nur Spec Dual Rear Exhaust for my GS300. It has not been put on yet.

My question is I want to also buy the XERD Stainless Steel Headers and Race Pipe.

Will the XERD Race Pipe connect to the Lecs downpipe or will the Lecs downpipe become a useless item? I believe the Lecs downpipe is also 50mm while the Blitz exhaust is 70mm. Will a muffler shop be able to conecct the two without hampering performance?

Thanks for your help.
