I installed skunk2 alpha headers and everytime I drive I hear a grinding noise. I have my rear mount upgraded to the 70a. I check and it's not hitting anything. What can it be?

is it a grinding or a hissing sound? The s2 alpha headers are notorious for hissing (leaking) at where it connects to the exhaust. I believe it’s from the crappy donut gasket that’s supplied with it

It's doing both. I didn't use the skunk2 donut I used one from an ep3

That’s kind of odd then, I can’t really imagine an exhaust or header causing a grinding noise. I suppose just take a closer look at the whole exhaust system and retighten some stuff here and there. Hissing is always a sign of a leak anyways

Was I supposed to completely take off the shaft half cover? Cause I put that back on

Following, doing mine soon. I bought a used Alpha header last year and finally got the full race exhaust to pair it with. Is there any extra hardware I'm gonna have to get since I got my alpha used with no hardware?

O2 extension, the hanger, new donut gasket and exhaust manifold gasket

Thanks man! Since the alpha header is 2.5in collector, do I need an adapter for it to mate up to the full race 3in?

Im not sure, I actually have the s2 header and exhaust along with the 3 hasport 70a mounts, but I had my mechanic put everything on cuz my cars undercarriage is rusted pretty badly. He mentioned to me that he removed a few things to make it work, but I don’t remember what they were. Sorry I’m not of much help
