Features & Product Details

This is the Grimmspeed External Wastegate 2-bolt Up Pipe Kit that features a 38/40mm external wastegate flange, and a Turbosmart Comp-Gate 40 External Wastegate. This setup allows owners to convert their internal gated setups to an external gated option. The benefit of an external wastegate is that it allows exhaust gases to be diverted prior to entering the turbo which will create a faster turbo spool. And because the external wastegate has a larger diameter than the stock internal wastegate, it allows the exhaust gases to be released faster which improves boost control, and it promotes longer life in the turbocharger. More importantly, moving the wastegate out of the turbocharger will relieve a large amount of turbulence that the stock internal wastegate will create.

Grimmspeed fabricated this up pipe from quality 304 stainless steel materials with thick 12mm flanges that will not warp. The flanges have been CNC cut for perfect tolerances and a flex section has been added to extend the lift of this up pipe, and it will allow for expansion and contraction without cracking, and it will lead to fewer exhaust leaks. With a good tune, users can expect gains of 15-40WHP when tuned for an external wastegate. 

This kit will include:

- Grimmspeed 2-bolt 38/40mm External Wastegate Up Pipe with Dump Tube.

- Turbosmart Blue Comp-Gate 40mm External Wastegate.

GS uppipe and ewg 3 months ago
5out of 5stars

installed a week ago and I love it!! The install took me about 6 hours cause it was cold out. Hardest part was taking the old uppipe out. TIP—— unbolt the down pipe, unbolt top nuts on uppipe, disconnect O2 sensor connector, remove 14mm nut to passenger side motor mount and jack up the motor about 2”, and drop the header. The whole assembly comes out in one shot. Remove the uppipe from the header while it’s on the floor makes it so much easier. Put your bracket for the wastegate while the Down pipe is disconnected, put the wastegate on the uppipe before install!!!! Install new studs on uppipe and install the uppipe to the turbo from the top. Don’t forget new gaskets for the header, uppipe and downpipe! Drop motor back down, install the nut for the mount. Install the header. Install dump tube and install the dp back and your golden. Also forgot you have to remove the tmic before all this btw. Don’t forget you need your tune for it also. Runs great ! No more boost creep!! Sounds amazing. Quality parts!! Highly recommended
