Hey guys, just a quick question. When i am running through the gears (usually when I am on the gas a bit haha ) every time I shift it backfires, just one loud pop. Car seems to be running fine and the backfire sounds kind of cool but I need to know what is causing it. Thanks guys

too rich, incorrect igntion timing, or somehow the exhaust valve is staying open too late.

Or an exhaust leak in the system somewhere.

Click to expand...

I was thinking exhaust leak, replaced both header gaskets, one was blown and then double gasket'ed the collectors...should not have any leaks...but i do feel i need to tune it, it may be rich....dont think the timing is off though..
