I want my truck to sound loud and have good tone to it. It is all stock. Should I put on a flowmaster muffler or dual exhaust it? If I dual exhaust it should I straight pipe it or have a muffler?

There are so many ways to go, best talk to a exhaust shop for your application. I have hooker headers with 3" Y pipe into a offset Mega-flow Muffler, 2.5 outlets (duels out the back) very end of exhaust it goes to 3.5 tips. But I have 400 hp. So any way, the smaller the pipe the more crackle you will get, larger pipe gives you a deeper tone, with the crackle under control so to speak.

No! Go to a muffler shop with a tube bender. Have them custom make you a 3" single exhaust. Use a 3" inlet & outlet cat converter & muffler. I like Raven products. Note: a single 3" exhaust system will flow more than duel exhaust. A side rear outlet is desirable too for towing.

The guy just wants a good sound, stock performance. I was just letting him know how different size pipe affects tone...

Yes I know. I did this to a stock 305 V8 Chevy sb pickup. It sounded so good! The difference from a trumpet to a tuba so to speak & cheaper custom made compaired to Flowmaster. 3" pipe makes more resonance.

If I just put on a flowmaster muffler what Inlet outlet size would I need?


I personally on your truck would go with 2.5" inlet with 2 1/4 dual outlet, I had duals from engine manifolds out the rear with my stock motor, & flow master on both sides, quiet when you need to be & giver a little and she'd rap. I don't see anything wrong with a single inlet and duals on the outlet. Exhaust tech. has come a long way. See if James pics up on this post & get his opinion also. All depends what you want.


My 3" single exhaust truck. Nothing sounded better.

I installed a flowmaster 40 on my first gen Ram. Factory 2 1/2" single exhaust 5.9 360 eng. It sounds fine. I'd prefer duals but couldn't justify the price. Flowmaster 50 is louder yet. You can get off cheap this way 50 or 60 bucks from flowmaster if all you want is a little BOOM for your buck

Say James, since you mentioned you exhaust, I have been paying attention to single exhaust on trucks. So I see...nothing wrong with 3" single, ran across one and it sounded great! I couldn't believe it, sound and performance! Coming from a dual exhaust guy...
