Maximus Posted March 8, 2005 Report Share Posted March 8, 2005 I have the Magnaflow on my truck, and the in-cab interior noise is not bad at all. I like the nice throaty rumble the truck has at idle, and the "balls to the wall" this thing has at wot, to me it sounds really good, and I felt a nice gain in hp too!

cadowns Posted March 13, 2005 Report Share Posted March 13, 2005 Well guys, here is some Flo-Pro feed back. I got the Flo-Pro 2503, Dual in/Single out. I am keeping my stock pipe and tip. I previously had a Magnaflow 12388. 5x8x24 dual in/single out. The magnaflow sounded great, but had really bad drone at 40 mph and at 65 mpg. I had the Flo-Pro 2503 installed yesterday. It sounds close to stock but a touch louder, and NO DRONE! Performance seems to be the same as the Magnaflow. I will know more about that when I get back to the track. I think most of us would like to have volume control on our mufflers, but Yes I am only dreaming. I miss some of the sound from the MagnaFlow, but not the sicking Drone. Got the 2503 @ Flo-Pro with free shipping, and the install was $40. Now, on to picking out a Torque Conveter CD Link to comment Share on other sites More sharing options...
SSMANIAC Posted March 13, 2005 Report Share Posted March 13, 2005 I'm a Flowmaster kind of guy. Been running them since the late 80s. I like the way they sound, and I've had good luck with them. I just stick with what works for me. <{POST_SNAPBACK}> Love my Flowmasters!! I tried Borla on my 01 mustang Gt and I wasn't impressed at all!!

Dirt.boy Posted April 7, 2005 Report Share Posted April 7, 2005 Has anyone heard the difference between the 2503 and 2504 with stock tips on our trucks? Their website show the 2504 alot louder, that probably where the got the 25 hp increase. Link to comment Share on other sites More sharing options...
smkdu Posted April 7, 2005 Report Share Posted April 7, 2005 Flowmaster man myself dual 3" Mufflers with Dual 3" Pipe straight out the back true SS style and boy do they ever turn heads when I feel the need.

shadowsniper3006 Posted April 9, 2005 Report Share Posted April 9, 2005 guys that have used the magnaflows, did you use P/N 14586 for the dual set up. That is the stainless offset/center at 2.5". Did everything line up? Or are the mufflers at weird angles under the truck? Thanks Brad Link to comment Share on other sites More sharing options...
smkdu Posted April 12, 2005 Report Share Posted April 12, 2005 You need a center and an off set to keep the pipes inline. Link to comment Share on other sites More sharing options...
shadowsniper3006 Posted April 12, 2005 Report Share Posted April 12, 2005 You need a center and an off set to keep the pipes inline. ok so one center/center and one offset/center? I went to a shop yesterday to see if they could just take the muffler out and splice in 2 stright pipes, but it was like a 100 bucks. So I'm just going to do this sooner then i was thinking.
