GrimmSpeed Hi-Flow Header Crosspipe 06-07 WRX & 04-07 FXT

Up until now all of you 06-07 WRX guys have been unable to swap in a higher flowing exhaust manifold crosspipe because Subaru decided to change up the design in those years. Well today is your day, we have created an 06-07 WRX specific HiFlow Crosspipe!!

WHAT IS IT?

This pipe replaces your stock exhaust manifold crosspipe that is very restrictive. 50% of your exhaust gases flow through this pipe so its very important to keep the this pipe flowing efficiently.

WHY ITS THE BEST?

This pipe has the same high quality GrimmSpeed design as the rest of our pipe line up. 

-Monster thick pure stainless steel flanges(many companies use mild steel flanges to save money but tend to warp over time)

-304 Stainless steel piping that is perfectly matched up to the gaskets for ultimate flow

-High quality flex joint that we use on all of our pipes with zero cracking issues to date!

-Direct replacement of stock pipe, fits like a charm.

FITMENT: 06-07 WRX & 04-07 FXT
