Summit Turbo Mufflers are loud and sound great.
Dont have a vid of mine runnin them but here is another one the vids arent the best and the mufflers sound much betterIf it was me I would go with at least a 2 1/4 inch exhaust if not a 2 1/2 inch. How much power is a stock worn out 318 really puttin out anyway. Just build your exhaust for future upgrades
