I have a 99 silverado 2500 ecsb no cats currently no exhaust. Im kinda torn between the magnaflow di 3inch so 4inch catback or dynomax ultra flow 4 inch cat back.. please chime in

 

If you are not running some form of boost then 4" is overkill.

 

I want the magnaflow pn#12594 dual 3 inch in 4 inch out.. only have a 4 inch tail pipe. Im thinking of running a xpipe where the cats where. Also thinking of putting dynomax bullets to replace the cats that I already removed

 

Mainly wanting the 4 inch tail pipe for the deep sound

 

i know you know this but stock trucks been running 3.5 for yrs now.....4" really isnt much larger and if you choke it up with smaller lead pipes then the muffler section wont matter as much

 

This is true however the selection of mufflers also goes to **** when you go to 4".

What gassers have factory 3.5?

 

3/4 ton bowties
Denali trucks

 

Anything with a 6.2L in it .

 

Anyone heard the magnaflow dual 3 to single 4 inch catback?

 

Thats up for debate on '' the best sounding '' people like diff things.. I always liked bullets, dynamax sounds great but depending on where the muffler is it will have a hard brap to it.. Had dyna, then swapped to a big *** edelbrock diesel muffler.
