I installed a Flowmaster #17421, it does not have the flowmaster sound. It sounds like a rice burner four banger. Any ideas?

Thats a bummer. You could lie to yourself and say you were inspired by "Fast and the Furious Tokyo Drift" but I am sure you still won't be happy. I have the MRT and I am quite pleased with it.

Ive got flowmaster american thunders, they look the same as teh muffler you purchased and the tip on mine are 4", they sound perfect nice and throaty, maybe yours aren't broken in yet.

I agree give them time to break in they will sound much better.

IMO, if theyre really that bad then all the time in the world wont make them sound good

402...I remember not too long ago when someone posted having a single magnaflow and being unhappy with it. Said it sounded ricey like you are stating that your flowmaster sounds. I am trusting you have a single? I held off on getting a single after hearing the single magnaflow sound clip. It sounded very bad. My only suggestion to you, if you want to STAY with a single, is maybe alow it some break in time. Or, and I hate to say it, buy another brand name...The Gt take off single sounds nice. So do: JBA, FordRacing Borla, and if you want to shatter windows, the MRT. All single and all with a very deep throaty sound. My .2

Rip it off and go Magnaflow and you will be happy for ever
