Really quite keen on the M4 Street Slayer slip on.
You cut the cat off and effectively make it a full system at the cost of only a slip on. I think it looks awesome, love the fact I doesn't need a rear hanger and sounds great.
I looked at an eBay listing and it said remapping is not absolutely necessary.
Surely it is? You're not going to have anywhere near the same back pressure.
Can the standard ECU just be reflashed to accommodate or will I need a powercommander or of the likes?
