Ok, so I bought my 06 Ram 1500 Qc 3.7l auto this year and recently decided it's time to do some work on it so for X-mas I'm gettin her a new exhaust system along with a K&N 57 FIPKII. This is my first American automobile and I have no idea how I should have it run. I've decided I like the Flowmaster 50 series I was just wondering what size pipe, single out or dual out, straight out the back or dump it. So many options what should I do? I mainly drive on the highway, and plan on headers next. I appreciate the help fellas.

 

i just put an exhaust on my v6. i wanted something that sounded rumbly without the apparent "raspy ricey" sound (at higher revs) that comes w/the flowmaster 40 on our v6 equipped trucks. i listened on youtube, decided to go with a flowmaster 50 delta with a 3" turndown pipe. i think it sounds really good. nice and deep. other ppl seem to like it too who have ridden in my truck. just my .02. good luck!

 

Are you gonna have them replace all the piping or just enough to get the muffler in and have the tail pipe routed like you want? Since you've already picked a muffler I would say dump the exhaust after the rear axle b/c it helps keep it from droning and replace the stock y-pipe w/ a magnaflow y.

 

I'd like to replace all the piping generally because I've read about how restricting the stock system is. Not sure the size of the stock pipes it's just too cold to get down there, any idea? What size pipes have you found give the best performance?

I'm looking at the y-pipe now gonna get one, thanks.

 

Well there is a sizing chart on magnaflow site here http://www.magnaflow.com/wideopen/performdata.asp at the bottom of the page, I think the stock piping is either 2 1/4 or 2 1/2 inches and then after the y it's 3 inches. The restrictions in the system that I see are the stock manifolds (jba headers will fix that), the y-pipe, the muffler, and maybe the cats. The stock piping is plenty big for the v6, but if you're gonna go all out I'd get the jba shorty's and some high flow cats.

 

You're the man! For right now I think I'll go with the stock piping wth the Magnaflow y and the Flowmaster Delta Flow 50 series. At least until I can convince my wife I need the headers. That probably means either she gets a new diamond or a set of new *****. More than likely a set of *****...thats just more toys for me. BONUS!

 

yep, +1 on the *****!

 

i have a magnaflow, this was my truck with a magnaflow and sidedump.

The 50 series was nicer than the 40. They are both ricy at 3000+ rpms. It has to do with the size of the muffler and the displacement of the engine. For some reason, the more displacement on a smaller muffler sounds deeper and meaner than less displacement on the same muffler.
About the headers, has anyone actually seen the stock headers? I dont think there is any flow restriction on the stocks other than maybe the size of the tubing. I can imagine that the wider the piping the more flow can come out, but at the same time it will come out slower due to more room. How much more flow can it come out if the size of the engine exhaust port if its the same as the pipe of the stock header? Will that make the muffler sound better? I dont know until someone tries.

 

Well I guess someone did
