Re: 3inch to 2.5 tips

if your making every 3" then have 3" muffler as well. Your bottlenecking your exhaust. If your getting 2.5 inch muffler, then just get all 2.5" piping. id say all 3" or GTFO

Re: 3inch to 2.5 tips

the I/D on the muffler is a 3 i think, the O/D is a 2.5. Flowmaster doesnt make a transverse muffler with 3 in O/D, i dont think.

if flowmaster doesnt make a 3" O/D then I would not recommend buying their products. I would go with a turbo muffler or borla.

X2, I went from stock pipping to 3" but I also added the RK headers at the same time, the guy at the exhaust shop was all for going with 3" pipping, said why not do it right the first time so you don't come back in 6 months to a year and upgrade. But I had already told him I was going to be running a Supercharger at the time. But having the exhaust before the muffler took off about 30-40lbs at least.

Re: 3inch to 2.5 tips

if you want the flowmaster, i don't think having a full 3" in and the 2.5" out is going to make a difference. your running duals out of the muffler right? if so, i say your fine.

Re: 3inch to 2.5 tips

yea running duals out. I dont think its going to make a difference, besides in the sound. Going from 3 inch to 2.5 tips seems to have less rasp.

Re: 3inch to 2.5 tips

It will make no difference. 3" into the muffler with 2.5" out is a common performance setup. The 3" in pipe has 7.06 square inches of flow area, the combined 2.5" output pipes have 9.8 square inches of flow area. So there is more output area than input as it is. Going to 3" output pipes will show no improvement in flow.

so your saying dual out 2.5 pipes has more flow area then 3" dual out? lol na, dont think so. plus it doesnt matter if its dual outs or not, its a y pipe set up so duals over single out will show almost no differnce.

Go 2.5 inch, in a couple year you will be mad you did, especially if you have future mod plans. So far people with just full bolt-ons and people with FI are telling you to go all 3". your gonna get rasp no matter what with flowmaster especailly at WOT.

that is not what he is saying. he's comparing a single 3" pipe cross-sectional area to a dual 2.5" pipe cross-sectional area.

why would you compare this? Im very confused why we are comparing 3" single to 2.5" double
