Gmpp catback bolt size?
 

Need to know the size bolt and nut that I need for the 2 bolts that hook up my stock downpipe to the gmpp exhaust flange. Hoping someone on here knows, would save me trouble than bringing the piece and test fitting individual nuts lol. Thanks :)

I bought a exhaust header bolt kit from Canadian tire. There's like 3 long threaded things and 3 short ones and 6 heavy duty nuts. The long ones worked like a charm on my gmpp. the threaded part is like welded into the stock exhaust system so you'll need all new hardware.

Thanks, think you can find me a link from there website? I don't know what to look for and a picture would help

Bump for more answers

i cant find it on their site. but its in a red package iirc and like 10 bucks. just go look in the automotive section where the "specialty tools are.

Thanks, but didn't find much on crappy tires site. Late night bump for any more answers. Im guessing the bolts are the same size as the stock bolts holding up a stock SS sc exhaust
