Ok well heres the deal....i have a 80 series flowmaster on the car right now, it's pretty good but i want something better....now i bought a dynomouth setup but i still have to weld in the bullet muffler to the 3" pipe....now should i 1) put the 3" pipe on there w/ a hi flow cat or 2) put the dynomouth setup on there

and does anyone have a dynomouth or loudmouth setup right now..if so how does it sound
