Here is my current exhaust system setup.
1) Doug Thorley Long Tube Headers Part# THY-481Y-LSO-C
2) 2.5" mid pipes/b-pipes with resonators (no cats). Pic provided - Custom made 409 stainless steel. https://www.cajunbpipes.com/?lightbox=dataItem-jj7ogl3t
3) JBA Y-pipe 2.5" but when it exits into the single pipe it is then 3" diameter pipe.
4) Magnaflow Muffler - "Round straight through" 3" inlet and 3" outlet. 30"case length and 36" overall length. - ( 6" in width )
Now I have a question for everyone to discuss. I am interested in trying a different muffler due to drone at 1500 rpms.
New muffler idea is a Borla straight through muffler 2.75 inlet and 2.75 outlet. 24" case length and 28" overall length. (7.75 in width )
Will going with the 2.75" inlet outlet muffler should I drop down to 2.75 diameter exhaust pipe or just leave the 3" pipe alone?
I know that the exhaust flow will be traveling through a 3" pipe and then drop down 2.75" inside the muffler and then exit out back into 3"
Will that disrupt the flow where I will lose HP/TQ?
