I got this up pipe as part of a package deal with my Perrin Header. This uppipe can be had for a bit more than what I got it for. I would absolutely recommend this uppipe for anyone considering going ewg. I didn't plan on going ewg because I didn't know about the ewg fitting until I purchased it. After deciding to buy this up pipe, I was very impressed on the care that went into making it. The welds were great and very industrial grade looking inside and out. Something I saw on the Grimmspeed up-pipe was that there is a brace that holds the ewg fitting to the up-pipe. I think this is great because wastegates can be very heavy. This one is ceramic coated so I didn't have to wrap it.
