I have a 305 tpi 5spd formula w/ dual cats. I have a flomaster catback designed for dual cats, but they are slip fit. How exactly am i gonna do this, because i can't weld. I really don't have the cash to send it to an exhaust shop. I'm also trying to collect the rest of the exhaust to do it all at once(headers and cats). I already have my intake beefed up with SLP runners and a BBK throttle body, my plenum is bored out and siamesed for the runners. I also bored out the base manifold, so the exhaust is really restricting my power, but i don't know what to do with the slip fit exhaust.

 

I heared band clamps are good heres a link.
