    I am thinking about changing my muffler/exhaust out and wanted some input.
    1- is there a difference in performance (hp/mpg) between putting a flow master muffler in where the stock one and have a 1 in and 1 out, opposed to putting a 1 in and 2 out and have dual exhaust?
    2- which is better brand flow master, master flow? I am not wanting it load matter of fact I like the soft grawl it has now but I am looking for more performance.
    3- some shops say I need to put a exhaust resonator to help get more preformamce. From my understanding that just changes the sound and does not help.

    like I said I am not wanting to wake the dead or even hear it in the truck but I know I will get some sound with the better air flow.

    Edit: Thanks for the correction, mod. I was wondering why it didn't make a suggestion when I started typing....

    You want more performance? You have to do alot of things. Just the muffler will not help much, except for better sound. Full exhaust meaning heads back! Then there are other things you can due to let it breath better and take more air and gas in at cooler temps. An super charger may be the best way to get performance but that is big $,. But so is doing everything else to try to get there with out one.

    Alot of Times people hear a louder noise and think they are getting better performance when it actually hurt it.

    That being said I love the ba exhaust. I have the budget system. I like noise. There is a little drone but it isn't that loud. I got the system to hear my truck and make it finally sound like a v8. I also have the sr model so I am sure the sound deadening isn't as good as other models

    My dual in/dual out Flowmaster Super 40 setup is near perfect. Sean and Brian will get to hear it Sat at ToyTec customer appreciation days. They can judge for themselves. "Matt, that setup really sucks!" Dang it.

    main thing when considering another exhaust system for use with stock exhaust manifolds is that you will want to keep with the stock dimensions as closely as possible thru the entire system. You will also want to control the drone somehow.

    BAmufflers has worked out a solution to both of this problems and wrapped it up into a simple bolt which is shipped around the world everyday:)

    Dirtydeeds,
    I have a quick question... In an earlier post you stated that Tundra's were designed to have a 2 in and 1 out exhaust. 1- so what does or how does a dual exhaust help the performance of the truck? 2- would replacing the stock with a aftermarket 2 in 1 out exhaust help or hurt?

    Hi. You want to blend the two banks of exhaust as smoothly as possible. Forcing them together into a muffler causes excessive back pressure. You will notice mid and top range torque loss.

    Our dual exhaust, and any other dual exhaust which uses a flow thru design gains 3-10hp and 10-20tq to the rear wheels. Unfortunately there is less low end torque compared to our single exhaust.

    Give a call if ya have any other questions. 760-877-4234
