i was thinking of just switching my oem muffler for a flowmaster 40 series on my 07 Scab 4x4. has anyone done this? and if i decide to do this will i get the really loud effects of a flowmaster catback system or what? and excuse me for the dumb questions but im kinda new to trucks and im only 16 lol

 

Alot of people do that, but i recomend going to your local exhaust shop and having them bend the tubes and making duals.

 

yeah i was thinking bout that too, do you have an idea of how much this might cost me?

 

I got true duals/2 Flowmaster mufflers/2 stainless steel tips out the back. Installed for under 500.

damn nice, how does it sound? rele loud? loud? and do u think it'll be a little more for me to do that cause i have an 07 Scab 4x4 new body style?

 

I just orderd mine w/ the supre44 muffler, 2 outlets and duals running out the back ( I will bend them out the sides at 90 deg) shipped for $240 from magnumexhuast off of ebay. It comes with tips (weld on), 2.25" piping.

 

thanks, this website is sooo hopeful to all us truck noobs lol

 

I paid $200 for a dual system. S/I D/O flowmaster with chrome tips under the rear bumper. It is loud until you gte to around 60. It then is a quiet "drone" from the rear. In fact, with the radio on, you cannot hear the exhaust on the highway form inside the cab.

 

nice but wats s/i d/o mean? lol

 

single inlet - duel outlet

one entry of the muffler and 2 exit holes from the muffler

 

thanks kevin

 

I just put a Flowmaster 40 on where the stock muffler was with a turn down right after. Sounds good to me.

 

the si/so will sound ok, but go with at least a si/do or a di/do to get the sound you want i have a flowmaster super 40 and it sounds great just cat back, im getting two maggie high flow cats instead of the 4 ford cats i got on there, ill let u kno how it sounds. my y-pipe just snapped on the manifold so all i hear is a loud junker that wakes up the neighbors.

 

Magnaflow is the way to go. You wont lose your low end power like you will with slowmaster.

 

I had a true dual set up installed with 2 Flowmasters and had No low end loss.
And that's when my motor was stock!
