One thing to take into consideration is that most muffler shops can not
do mandrel bending on the tubing. The typical muffler shop "crush 
bender" will greatly reduce the flow of the tubing, you would probably 
have to go to at least 2 3/4'' tubing to get the same flow as a mandrel 
bent 2 1/2" system. I would make sure that the Blaufernugen system is 
mandrel. It is possible to fabricate a system using mandrel u-bends, but 
it is time consuming (expensive), this is what we do for all the 3" 
turbo systems. We've had godd luck with the Magnaflow mufflers-well 
built, low restriction & reasonable noise levels.
