Exhaust help on my blaster.

[PWCMX]

I'm trying to put a 760 couch motor into my blaster that has a blaster factory bpipe (I believe). The exhaust manifold has holes for 8mm bolts but the 760 engine uses 10mm bolts. What do I do. Is it safe to drill out the exhaust manifold? I don't want to ruin it.

Install timecerts into the 10mm threads. This will let you use the 8mm bolts.

Probably a good idea to port match the manifold as well? Sounds like a 61x Manifold.
