In that case, straight through side pipe will give it a nice cackle, leave the engine stock, it'll last for ages anyway, if you happen to pop it get another engine and drop it in over a weekend for next to no $$, strip it all out and spend a bit of time, effort and coin on suspension if you're really keen, otherwise, just wring it's neck till it cacks it, fix, rinse, repeat.
Has fun :P
