Flowmaster super 40

[Hemifatboy]

On the flowmaster web site they say this is a new muffler as of August 1, has anyone bought one yet and if so how is it , when I enter my truck in their filter it comes up with this muffler but doesn't say if it's a direct fit . The description looks promising

I used to run regular 40 series on my GMs and fords and really liked them. Then I ran a super 44 on my last GM with 5.3 and LOVED it.

Unfortunately I have no experience with the super 40 but I bet it's sweet if it's anything like the super 44.

It's not gonna be a direct fit because your replacing an elephant sized muffler. With that said I put on a super10 and it took like 45 mins. I got the 3" in double 2 1/2" out. Bought a piece of 3" pipe and a 3"clamp, 2 pieces of 2 1/2" pipe with clamps and a couple 2 1/2" to 2 1/4 adaptors. I believe it was four 2 1/2" clamps and two 2 1/4" clamps.

This is new it says 3.5 in and out ?

 

[gassersarentdead]

What's your truck?

 

[gassersarentdead]

Mines a '12 and the stock pipes are 3" in and 2 1/4" out.

This is new it says 3.5 in and out ?

I don't know alot, but I don't think that's gonna work unless you're running all new 3.5" pipe.

2015 2500 6.4

Oh, I dunno then.

If the inlet and outlet pipe sizes are the same it will fit. You will just have to adjust the pipe length on the inlet or outlet side to make up for the difference in muffler body dimensions...

But aren't the pipe size on these 4th gens 3" diameter?

pick shows what I think to be a super 10 and a extension pipe infront of it to fit the flowmaster

 

[gassersarentdead]

I don't know what they are on a 6.4 2500. On my 1500 it's 3" in and 2 1/4" out.

 

[Hemifatboy]

I think it's all 3.5 after the Y , trying to check

 

[Hemifatboy]

3.5 pipe looks correct , I guess it's just so new it hasn't been tried yet , can't even find a review

cant speak for a ram, but i had super 40's on my 06 GTO with the 6.0 LS2 and it was the best sounding car ive ever owned.

Has anyone tried this new muffler on a 6.4 yet?
