Grimmspeed's Crosspipe for the WRX and STI has been made with 321 stainless local raw materials. The flex joint is 321 Stainless Steel w/ an Interlocking Liner and tubing is a heavy duty 14 Gauge 304 Stainless Steel(competitors use thinner 16 GA) that has been CNC Mandrel Bent and finished up with a nice brushed finish. Our flanges are made out of 1/2" 304 Stainless Steel and are fully machined on all sides(competitors typically just laser cut flanges for cost reductions). We also put a nice bevel on the edge of the flange so you don't cut yourself. You're welcome. The insides of our flanges are "cut-back" to allow the pipe to rest inside the flange which gives you a nice flush mating surface thus allowing optimal flow through the pipe. Heck, we started as a Porting company after all....we take pride in exhaust flow quality through our pipes. All fabrication is completed by our Welder/Fabricator who is certified in Aerospace Welding...yeah, he knows his stuff. A bit of overkill using an Aerospace Welder you say? Well the Crosspipe is put through some very harsh environments so we wanted the best for the job.

Subaru supplies its turbo owners with a tiny little crosspipe from the factory. 50% of your exhaust gasses are passing through this tiny pipe and, well, that's just a problem. Crosspipes run in very harsh conditions when bolted to your car so it is important to use high quality components otherwise you risk fatigue. Do not worry though, GrimmSpeed has a solution for you!

Experience was unique.

Customer service was excellent. Shipping was very quick. I first ordered wrong part and that was resolved rather quickly. Reordered with a quick ship. It was an easy installation. It's nice upgrade and look.

Great product

Got this because I was unsure of ehl or uel. Sometime in the near future I will be upgrading to a killer b. But in the meantime for the price this has done the job! Ceramic is a must! No wrapping needed.

Replaced the older V1 crosspipe I had already with this. The infamous chirping sound is gone. Only minor gripe is that the pipe is not tapered to the inside diameter of the flanges like it was on the V1, so there is indeed a tiny step going in to the pipe. I have the grimmspeed ported headers, so maybe the step is not there when installed with the stock headers.
