Yea I don't want to **** on you... But I've seen it countless times. Guys ditch a chambered muffler in favor of a straight through design and gain power.

Props to the forum sponsor for sticking up for his product. I have to respect that. Doesn't flowmaster offer some straight through mufflers?

Even the 80 series?

Yes we do. Our Outlaw Series race mufflers are a straight through design.

Yes, Flowmaster engineers have designed each series of mufflers with maximum efficiency in mind.

do your headers and a real dual exh, you should move to the factory
larger rad with dual E-Fans , 170 deg stat also. get a good tune
wires and plugs would prob help if yours are still original factory ones.
CAI of course.

i call bullshit on that. all the ennginers do is for sound. i can search google and get pages on people taking their flowmaster off and gaining 20+hp. **** i even drew up a layout for a guy on another board for a pair of mufflers that he wanted to build and he did. **** sounds nice for me.

Coming from a guy that just built up a 6.0 that cost over $4,000 I think if I did it over again I would just turbo my 5.3 as they are cheap if they blow. My next plan is to turbo my LQ4 but I guess whats your budget. LS motors get expensive really fast.

also when i ran one on my old truck it droned like a **** at around 1500-2200rpms. basically cruising speed. i thought your engineers spent time and money to lessen drone. i know when i went with a spintech/pypes race pro the drone was a lot less.

at least i know with my magnaflow my pipe is the same diameter all the way threw and is stainless steel so i don't need to worry about it rusting inside out.
