Hello fellas I got a 4.8 silverado and I just got done installing 216/220 cam I got stock manifolds but 3 inch piping after the y pipe and it's dumped with flowmasters but I ready to upgrade to match the cam what do you fellas recommend

 

Get some LT's and an ORY and preferably a better muffler most on this site love magnaflow, i like dynomax ultraflows myself, and you will have an exhaust setup that will make great gains now and can grow alot more as well...

 

long tube headers and a off road y pipe for sure. also a good tune

 

everyone nailed it on the head, set of long tubes and off road y pipe, and change your muffler, get tuned should help tremendously. To be totally honest, i had a flowmaster super 40, and truck fell flat on its face, sounded good at idle, but never what i wanted, i then went to 14" magnaflow, that was years ago, now im a bit wiser lol, i run a 3" dynomax bullet into a tbss muffler thats dumped behind the axle, getting mine retuned today, put a tr224 cam in yesterday

 

you are choking that cam big time! do what they said and let that engine breathe easier, then tune it and it should really wake up.

 

Thanks guys for the advice I have already gotten it tuned by flaco performance since my truck struggled to keep an idle and already feel a world of a difference so after I install all of the exhaust system should I get it retuned?
