RPI exhaust bolts

Nate4641 · 11-03-2012, 05:23 PM

I just got a set of used RPI GT mufflers but they did not come with the bolts that are supposed to come with them. Are these bolts necessary to install the exhaust and if so are they something special or can I pick something up at home depot that will work?

Funny, I just bought the RPI scoop and it didn't come with the mounting screws...not that this helps you..

They ended up being 8mm x 50 bolts with 1.25 threads. Just in case anyone else runs into this issue

It sounds awesome! The drone gets a little annoying around 50-65 since 6th gear isnt that great at highway cruising. Aside from that, it sounds just like I thought this car should have sounded from the factory. Little taps of the throttle to rev match while downshifting sound sick. It definitely isn't the best option for most people since it is so loud and the drone is annoying for daily driving or long trips. I dont drive my car much so I love it.
