Flowmaster Vs Spintech

Well just learned about spintech and wow apparently they out do flowmaster. Anyone know if this is true? I've been a flowmaster fan for a long time but spintech seems to be a bit better.

yea if you place them on a flowbench (for flowing heads carbs ect.) like most glass pack manufactures due. Last time I checked my car didnt run on a stream of cold air.

Re: Flowmaster Vs Spintech

I have a spintech and it is the best sounding muffler I have ever heard. Makes great power also. I have 2210s going into a single 4 inch over the rear and then two 3s out of the spintech and it is awesome.
