February 6, 2007I have flo pro, dual in dual out. It sounds pretty good IMO.
February 6, 2007Truckingbig58, that is exactly what I did. I believe they only have two mufflers that you can do that with (at least for hd's) if I recall correctly, the 2504 and 2506. I got the 2504 which is quieter than the 2506. I was worried but in cab drone, but I kind of wish a little that I would have gotten the 2505 but I did not want the dual pipes, I think with my bumper they would look bad. But the 2504 with all the stock pipes sounds good, just quiet until WOT.
February 6, 2007oops, sorry, i switch the 2506 and 2504. I have the 2506, the 2504 is louder.
February 7, 2007Finally some people are getting the idea about Flo Pro. They are bomb proof and sound good.
And since we all forget what its supposed to be about-they flow like mad.
I have had duals and single in/dual out V Force (flo pro).
good choice, and i never heard mine until it was driving away after being sold-i ran after it to get it back!
February 7, 2007ok just to cure mine and everyone curiosty... i went by my buddies muffler shop... the 2505 FLO-PRO i took off the duel 3" tail pipes that went to the right rear after tire and just dumped both 3" after muffler... it's just a small margine louder then when they were exited out the side..still not droning the inside of the truck.. so ive had the same 2505 hooed up three ways now and i like the dumped down and off to right side on a 45 degree angle the best
March 5, 2007I am running the FP731 on a 04 Tahoe Z71. I have had it for 1 1/2 years now and it is going strong. I often wonder what the V force would sound like....
March 6, 2007I had fp740 on 5.7 97 chev sounded great.
Flo Pro (V Force-little louder but smoother so doesnt seem as loud)
FLO PRO will take over the world of mufflers when people realize that for once, a muffler does enhance performance!! These ones do.
True duals from stock-same hills truck didn't even kick out of OD anymore-now thats power.
