I have a Blitz Nur-Spec R cat back and I would like to replace the Axle back section of the Blitz with a full 3" Stromung axle back. I am hopeing someone here can tell me that it will bolt up without modification. I know the flanges are the same but I dont know if the axle backs are the same length from tip to flange and I dont know if the front pipe of the catback on the Blitz and Stromung have the same bends. Any help would be great.

Thanks.

 

That should be no problem. The flanges are the same.
I am running a Stromung twin tip, and my buddy is running what you are. Mine sounds a lot better, and he has to use the silencer insert, or risk getting pulled over by the cop's.
