break In Flowmaster

[BobbyVenture]

How long will it take for the delta flow to fully break in? its gettin louder each day lol

You'll notice the sound changing slightly over the next month. It mellows out nicely as the exhaust deposits build up.

it's all metal! how can it break in?! you'd have to have a lot of carbon to change the tone. how is the cab resonance? low, med, loud?

I can honestly say I have never heard of having to "break in" a muffler.

you dont have to break it in, however when you install a new muffler the sound you get immediatly is not the sound you will have in a few thousand miles, as the muffler gets used its tone will change a bit

you dont drive any differently to break it in

yes, flowmaster's have to break in. I had a 40 on my cav for quite a while, but it got too loud for me. So i replaced it with a flowmaster delta 50, and its taken about 2 weeks to break in. Once you put about 1000km onto it, itll we stay the same tone.

ROFL, Muffler break in. HAHAHA

call it what you will, but Flowmaster's will keep changing tone, getting progressively louder & deeper for about the first 1000km you put on them. Ive had 2 and they have both done the same thing. Also everyone i know who's had flowmaster's will say the same thing.

i put a muffler on my 02 lancer and it sounded a little raspy when i first got it, about 2-3 weeks later though it mellowed out some and sounded pretty good.

my dynomax bullet on my truck also got a lower tone and louder as i put more miles on it. i like it though...sounds very hot roddish

it changes tone as it heats up
