so brand name exhaust sys are expensive. so to avoid shelling out alot of money i am scoping out ebay but most of the systems are with 2.25 or 2.5 pipes. Rams have 3 inch. What will hapeen if i get the smaller diameter pipe???

 

I'm having a local muffler shop install a cat back with a flowmaster 50 and a nice stainless rolled edge tip for $200.Seems like a good price especially when comparing to some of the Borla, Magnaflow and Gibson systems. The tip will be welded on instead of bolt-on which IMO will look mnore finished.

 

i have a 2005 dodge ram with a 4.7 v8 i got flowmaster 40s put on at a local exhaust shop for $250. they are 2 1/4 in. pipes with 2 1/2 in. rolled tips welded on. It sounds GREAT! People think it has the hemi in it.

 

listen to my 05 ram with the 4.7 V8 with flowmaster 40s.

what mileage are you getting.

 

im afaid that i will f*ck up my enging or not have wenough back pressure (or too much) if i dont use 3 inch outlet pipes off the muffler....

 

i have a 06 4.7 with flowmaster 40 series. 3 inch inlet and dual 2.5 outlets. gas mileage didnt improve much to notice. at sounds awesome and runs great.

 

im raising the front. i dont know about th eothe rguys. i was just going to go 2 inches with the tuff country spacers.

 

im getting about 13.8mpg city with traffic. Putting 3 inch pipes wont f up ur engine at all.

 

If you are worried about cost you could just buy whatever muffler you want and have it welded in. You won't mess up your engine going to the smaller pipes. Your gas mileage isn't going to get any better either(it might get worse from stepping on the gas to hear it)but it sure will sound better
