exhaust choices
I want to make a correction to a thread that I posted to earlier this week. I've been a big fan of FlowMaster mufflers for a while now and found that they hold up well. I did have a problem once with a 360 CID 1999 Dodge P/U. I put a larger (V-10) catalyst and Flowmaster on it and it droned me to death!
Now that I've had some more time behind the wheel, I want to set the record straight about the 50 series FlowMaster. It sounds REAL NICE
at idle (kinda lopey...like it has a mild cam), but once you get on it....well, that's where personal tastes and tolerance come to play. At a steady cruise of 2000rpm and below it is unobtrusive (quite tolerable). But at a steady cruise of 2200 to 2500 rpm, it sounds like a Ricer exhaust!
. The six becomes a four (sounds like a coffee can full of angry bees)! The power is OK, but it really sounds like SHIT!

I've been playing around and doing some research: I added a K&N style filter (can REALLY hear intake air when engine is cold), that reduced the exhaust noise a little. I also reread gojeep's page about reducing the tailpipe diameter to speed-up the velocity of the gasses thru the system. I will cut-off the nice SS tip from my 2-1/2" tailpipe
and stick a 2-1/4" testpiece on there to see if it works for me. If not, I will look at resonator tips to help get rid of the droning and "bees". I am alos going to be doing a gear change (4.10's) soon, that should change my RPM's at cruise (maybe out of the "Angry Bee band") and create less "lugging" of the motor (which my 3.55 gears and 31" tires tend to do). Last resort, I will cut out the Flo and install a DynoMax in it's place. They have been recommended on this board and from guys at work.
I thought I would repost this to give and honest and detailed (although personal) analysis to a question that pops-up a lot on this forum. Otherwise, the FlowMaster isn't a bad OFF-ROAD exhaust. A friend of mine here a DCX builds and races at the strip, he told me DynoMax - "hands down!". They produce more power and no droning!
