I have longtube headers, 3" exhaust back to a flowmaster y-collector 3"in and single 4"out with a magnaflow race series muffler

 

I have a 4" exhaust going from the downpipe and its pretty loud too. I have a 20" case magnaflow.

 

I have no cat, just 3" Downpipe in the the 4" muffler and tail pipe.

 

Atomic what three mufflers are you using?

I don't mind loud so long as the majority of the sound is going out the tailpipe and not up the back of the cab and into my ears like its doing now.

Hows the quality on the 3" in 4" out flowmaster Y collector? Is it fairly heavy gauge or not?

 

2x 6" round by 14" long 3in SI/SO magnaflow
1x 5x11x22 dual 3" in, single 4" out magnaflow

I personally dont like the flowmaster Y pipes, I used to have one and it added a lot of drone to my exhaust.

My exhaust basically sounds stock at anything but WOT, even inside.

 

I hadn't thought about using a dual in single out muffler as a Y. I guess that might work but I would rather stay with one muffler if I can and maybe a cat later on.

From the look of it the transition on the flowmaster Y doesn't look quite as nice as I would like. I may have to try and make my own Y or keep looking and hope someone makes a nice 3 inch in single 4 inch out Y.

It works very well. Shown to make 15hp on the dyno
