1500HD Flowmaster exhaust

[samckitt]

Was looking through a Flowmaster catalog I got the other day & noticed they have a kit for the 03 1500HD crew cab short bed. It consists of (I beleive) cat back setup, to a dual 3.5" input 70 series muffler & then to a single output side exit 3.5" pipe with a 4" chrome tip. Has anyone used this kit, or those of you with flowmaster muffler(s) just replacing the muffler or what? Also curious if anyone has dual rear exits & not single side exit.

 

Thanks,

Scot

I have flowmasters on my truck..I have 2 not 1..true duals from front to back..if your only gonna use a single muffler I would just stay stock in my opionion....Gun

On the 4300 trucks like the older ones, is it true you have to use one muffler for the "dual exahust" setup. I have a 94' 4.3, and was considering doing this. I was told I could only use one pipe.

Mike you could do it but you would have to add a catalyc converter...Or you could use the single inlet with the dual outlet

on my 95 i took it to the shop and had a single inlet dual outlet and dual pipes running around the spare tire and out evenly spaced under the bumper

sounded KILLER but i had to take it off and opt for a single pipe when i dropped my truck to the ground!

i still have the muffler if you are interested make me an offer - i can snap a pic if necessary!
