Exhaust job

Postby Stack_em_up » Sat Feb 01, 2014 12:54 am

I have a 2003 chevy with a 6.0 in it and I want to pipe it out. I don't want it aggressively loud tho. I was thinking about putting in the flomaster 50 series in. The dual in dual out. Anyone have any input for me?

I wouldnt run a "blowmaster" as they are often referred to. dont sound as good and do not have the flow of other mufflers.

stay away from chambered mufflers. check into Spintech, Magnaflow, and Borla
I'll be going to Spintech 6000 series muffler soon behind my 6.0L that has headers as well. Should have a very nice tone and really only get loud when you step in it.

tons of great info in there- http://www.gmfullsize.com/forum/showthr ... 8&page=270

I would go with a good chambered muffler over a straight-through/glasspak design. The chambered mufflers give power that is just as good or better, and they control sound better in general. They also tend to last longer, soundwise.
I'd look at the Hooker AeroChamber mufflers, if I were in the market for that kind of thing.

And, go with two mufflers, not one. Otherwise you're creating a bottleneck.

Those are my suggestions. The choice is yours. :thumbsup:

the correct sized muffler and pipe will not need two mufflers. true duals like I have currently SUCKS, and has a negative effect on the scavenging effect. Chambered mufflers cant give as good of power/ flow because the chambers hinder flow, although some may be close in flow to a straight through but i can bet not better. If you do run dual mufflers, make sure you have a X or cross over pipe. the LS motors really prefer a single pipe, not to mention a single pipe dumped over the axle looks and sounds much better.

LOLZZ its a gasser not a diesel!

diesels actually sound decent straight piped (but it's illegal)

gas trucks sound like doo doo and loose performance when straight piped, unless they are running a crazy forced induction set up and crank out serious HP. and also illegal for street driven rides.

I had an 03 with a 6.0 not long ago I had the exhaust done tru dual from the cats back 90s to tips oh that thing kackled like nothing I've ever heard. Moral of the story if you don't want loud leave the muffler on or put one on if you're doing exhaust. Got a ticket first night I did the exhaust.
