I think my car is a little quiet now with the flows on it, what i did is get some race readies from summit weld them in before the mufflers and use electric cutouts, you can close them for quiet mode, tune them to a sound level, or just run them wide open whenever you want. I paid $213 for dual 3" electric cutouts that should be here next week.
BTW i ran with uncapped cutouts last night, and OMG IT WAS FRIKIN AWESOME, the car sounded very very very evil, it sounded like test and tune night at the track in my city lolololol
Flowmasters, MAC & all the other cheap brands= drone crazy. (I've had them all, I know )
So what I did was delete my mufflers on my 94 GT, and ran sidepipes. Insanely loud onstreet, but NO drone. I loved every second of it. I made my honda buddies sad too When I finish this new engine, I'm putting Flowtech Warlocks on. They've got built in cutouts. Oh and I never had a cop look at me crosseyed.
It's usually hard to have two different cars in one; the best solution is to have two vehicles (cutouts may be a cheaper solution).
Most of the responses I've read who are "loud exhasut happy" don't have real loud cars on the highway daily. It's nice for a car that you choose when you drive it, but sometimes sucks when you get a headache from it. Setting off car alarms is fun too, but I got tired of that as well.
Ah...what am I saying...my truck is loud too, but not obnoxious.
