Great Bolt On, Aggressive Sound! 2 months ago
Love this Bolt-on!! This header has a great "boxer" sound and the lower end power gains are very noticeable! Comes with larger than STI factory up-pipe (doesn't bolt to stock up-pipe anyways), titanium heat wrap, and fasteners to lock it all in (fasteners are REALLY short and some were doubled, buy hose clamps as a backup plan). WARNING: If you have a cat less downpipe and a "louder" exhaust like an Invidia N1 cat back, you might think it's kinda loud. Hope this info helps!!

Beautifully crafted  5 months ago
Okay first mistake do not heat wrap it untill you fit test it I got lucky and mine mocked up perfect without adjustment but this header is extremely well crafted and just pure quality running a Cobb stage two tune with tomei catback, this combo is the perfect iconic boxter rumble in my opionon I did lose about 2 lbs of boost only because I have not gotten it tuned yet but my STI seems like it's running happier now I use to get after flare when I would release my throttle at WOT and no longer am having that issue. Install was easy I'd suggest just removing your downpipe and the whole cat back this is the perfect opportunity to make sure your exhuast alignment is good and you and address any exhaust rattles with the excess of heat wrap you will have left over the worst part is putting the bottom heat sheild bolt back in remember to follow the tightening pattern torque and leave everything loose and start from the front of the car back. Easy install and results are worth it enjoy

Unequally awesome! 7 months ago
These headers sound great! They were easy to install, given you have the right set of tools, and they unlock that subie rumble that everyone will turn their heads to see

This header is awesome. Flanges are thick, welds are perfect, and the quality is impeccable. Also came with heat wrap. The only con I would say is that it’s kind of a PITA with trying to get the top bolt and nut on the 3- bolt flange going to the up pipe. Other than that it is perfect. I also didn’t use the up pipe that is in the kit. I am running the 3-bolt Grimmspeed up pipe EWG so i will hang on to the other one till I need it. Thank you RSD.
