96 exhaust

[MAC88]

Looking for the best way to install an aftermarket exhaust system or muffler on my 96 K2500 ext cab long bed.

 

I have dual 3" pipes going in 6" on center and a single 3" offset going out. All the mufflers seem to have a single going in and a dual out or they are the wrong size pipes on what seems to be the right set up.

 

I dont mind using oem replacement pipes with a performance muffler or a whole system I simply don't think its worth the $400-500 they want for the setup so I am lookin for alternatives

 

is there a y collector to convert my dual inlets to one single 3" or 4" pipe so I could run a single all the way back

 

Any and all thoughts appreciated
