Thats a good question.. though, ya cant really use the 'how do they flow?' and ' i want a quiet exhaust' in the same thought.. theyre indirectly proportional. You get one or the other. period. i researched my BUTT off, and spent about an hour on the phone with dynomax tech lady, drillin her about sound, flow, resonance, drone, tubing diameter yadda yadda yadda.
Now, there are mufflers that
are quiet, but flow
RELATIVELY good for their quietness.. but key phrase" "flow good for THEIR quietness"
Or, the mufflers that are really high flow, but are kinda quiet for
THEIR flow rate.. It's a pretty delicate balance actually.
Though, considering our cars have a HUGE restriction in the exhaust, you
can potentially have the best of both worlds, with a
relatively nice flowing quiet exhaust, but run a cutout in the system, allowing you to do whatever you want, whenever you want to
That's what im going to do next season. That way, if you wanna take the girl in the car to the car show, and just sit and gab, run em closed, or if its just you, on the local cruise strip lookin to beat on some mustangs, run em open.. its all on you.
