spintech mufflers
I've had about every exhaust setup you can think of (straights no cats, with cats, turbo tubes, magnaflow, borla black series, etc.) Currently running flowmasters 40 series. But I have not had the ones you are talking about. Thought I could be of some help if you were wondering about anything else.
thanks for the replies. i like the deep tone/rumble the magnaflow muffler gave me, but i expected a little more volume. its a simple si/so magnaflow welded into the stock piping. maybe its the stock piping keeping the volume down?
Well depends on what you like... but when I had the turbo tubes w/ cats, it sounded pretty good once warmed up (it did pop a little on cold start) and if you like a chambered sound, go with a single chamber muffler. I have dual flowmasters right now (2 chamber) and its on the quite side. YouTube can be helpful, there are a lot of setups on there.
