what is the flow diff. between spintech and flowmaster i am looking at
spintech sportsman Street XL ---- 3457XL

List Price: $125.50
Online Price: $119.50

Inlet Size: 3 inch Dual
Outlet Size: 3 1/2 Inch Center
Case Size: 4 x 9 1/2 x 16

Description:
Description:Our XL series was developed to be the quietest muffler we offer,for most applications,(Truck R/V is actually the quietest) yet still has a unique aggressive sound. designed after our cross flow but with single inlets/outlets up to 3 1/2 dia. Description

____________________________________________________________________
I have the Flowmaster 50 Series™ H.D. muffler is Designed primarily for today's higher horsepower trucks such as the Dodge HEMI. This muffler will perform well on various vehicles when a deeper, more aggressive tone is desired. This new muffler features a 4.00-inch internal design, which is ideal for trucks with modified engines. It is built from 16 gauge aluminized steel and comes with various inlet/outlet configurations.

50 SUV doesn't drone. You can't judge them all by one model. Only 2 HP difference between the two and the Spintech's louder. No one has ever shown actual proof of the "horrible" affect of a Flowmaster. Until I see numbers from a dyno to prove otherwise, I call it Groupthink. Prove me wrong. I personally love the sound of a Flowmaster and the dyno numbers above make the HP a moot point. Not trying to be nasty here, but I'm also thinking for myself, not what everyone else has "heard".

seems like all those mufflers do jack for hp increase, youll never feel 3 hp anyway, just get the one you think sounds the best.
