    Hey guys fixin to weld in some Spintech Super Pro Street 9000 mufflers on my stock RV 454. If anyone is interested I'll post some sound clips of before and after. Has flowmasters on it right now but they're way too quiet for me.

    Which Flowmasters are they? I have a stock 454 with super 40's (2 chamber w/larger case) and a crossover. This is just an idle clip, but it's pretty throaty when you accelerate.

    Not sure which flowmasters I had they were on it when i got the truck, not near as loud as yours. Pretty big mufflers. Threw the spintechs on not going to run tailpipes for now. The cell phone quality doesn't do them justice. They are pretty damn loud. The truck sounds like it should now.

    To me it sounds more mellow and deep at idle.
