Additional notes:

Our 3.5" systems will have a transition piece to mate up to 3" testpipes/downpipes,

YOU MUST EMAIL at time of purchase to have a 3.5” flange instead. The 3.5”

flange WILL NOT mate to a 3” flange!! 

If a test pipe is purchased with the cat back system, the transition will be placed at the entrance of the testpipe by default. If no testpipe is added to the order, by default there will be a 3" flange utilized with a transition to 3.5" at the beginning of the system.

There will be no special request coloring options for these systems. Each system may be colored slightly different from one to the next. If a special coloring is desired, please email the request and a fee will be assessed.

All systems are built to order; please allow up to 4 weeks for completion.
