So, do yourself a favor and get the Grimmspeed OEM hardware kit for the studs that’ll back themselves out of the turbo and the 2.5” to 3” adaptor (if you’re using your factory mid-pipe) along with some PB Blast and you’ll be golden on the install. Just have some patience.
Very good downpipe!
I had 2 nuts seize on the turbo studs. That was a paaaaaain in the butt. But besides that, the rest of the installation was fairly easy. The only downside was that the front O2 sensor was a little far to plug in. So I had to unscrew the harness just to make it reach and then ziptie the wiring to the heat shield, at least until I get an O2 sensor with a longer cable. Besides the pains with installation, the car sounds amazing. I was going for sleeper sounds which this totally does the job. You can hear turbo spools but it's not overly loud. I'm running with stock catback and AEM intake (purchased Grimspeed adapter to fit to stock catback). You can feel that the car just wants to go now. Getting some pretty good torque even in 5th and 6th gear.
This is worth the price. Easy to install ( minus that stubborn stud nut on the top right), everything fitted together nicely, and it sounds amazing. Goes great with my Cobb accessport and Cobb intake!
