Can you use the stock spring bolts with the hks carbon ti? If not what size bolts do I need?

 

I did and it worked out pretty well. You have to push kinda hard on the bolts so you can get enough threads to get the nut on the other side, but once its threaded, its really easy to tighten all the way

 

thank bro ill give it a try

 

also the flextube on the midpipe is kinda frayed from being scraped and I think its causing an exhaust leak but Im not sure if its from that or the bolts do you think I can use some header wrap and wrap the frayed part or would I have to take it to an exhaust shop and have them chop and weld a straight pipe
