this mostly pertains to you flowmaster owners. does a flowmaster add power to our trucks? if it does, what kind did you get? (i.e. 44, 40, 50, super40...) in/out (dual, single??)?

 

i voted yes. i have a v6, so i notice power boosts with everything.

put on single in, dual out flowmaster 40 and cai same day. noticed more power in higher rpms.

 

I had it on, but too loud. I'm not sure what I put on after, but it's not as loud and still is almost too loud. Power, It's hard to tell with a hemi

 

Flowmaster 9530560 single in/out & no resonator.

Seems peppier & I like the low tone.

Reminds me ofmy younger years.

Yes
Got the 50HD single in / Dual out.

If you go with either if the 40's you will want to go with true duals. The 40's are louder, but they restrict more if you use a single muffler instead of 2.

 

i have a 2005 ram4.7l and i had my exhuast guy take out my y pipe and make me a dual inlet dual outlet super 40 and its awsome i love the sound and the power

 

Flowmaster 40 Single In Dual Out

 

I have the Flowmaster Super 40 Single in Dual out. I believe it added HP but can't be too sure as I had all the extra crap cut out at the same time which probably helped more then the muffler.

 

i cant say i felt much in power gain, if i did they were minimal. i have a 40 series si/do and a new y-pipe with all resonators taken out. it sounds real nice and loud sounded even better when i added a volant intake to the mix. its real deep and throaty. not to mention it looks real nice coming out 45ed behind each tire with big 4 inch slash cut tips. gets people looking and guys in minivans droolin when ya get on it.

 

flowmaster is a restrictive chambered muffler... sounds good though... i think the only one that might flow alright is the 50 series
