Grimmspeed Up-pipe
Hey guys. I have searched this topic and keep getting mixed reviews. I am seeking some experience with this. Here are my mods: Grimmspeed cold air intake, Grimmspeed 3-port BCS, Walbro 255lph fuel pump, Perrin TMIC, Invidia catless downpipe, Invidia Q300, and tuned with Torqued Performance stage3 tune. My question is, will there be benefits installing the grimmspeed up-pipe? I have researched and it seems to be mostly reviews from those who have 02-05 wrx's. Any one here who has an 08+ seen an improvement and if so, what?
Thanks
Ray
