Dipping a toe in the rabbit hole...

I’m running a FI CBE with 12” resonators, stock manifolds and cats and get the stink eye every time I cruise the hood now, mostly due to its Hilly and there’s just now way to get in or out of here “quietly”.

Do I have options other than test pipes? Will this melt Quality HFC’s?

Is there a quieter solution?

PS: unfortunately, moving is not an option at this time.
