My Y block powered F-100 needs a muffler, and I was wondering if any benefit can be gained from going to a bit of an upgrade- say a three chamber Flowmaster. The truck will stay single exhaust for now. I want a quiet muffler, but thought that while I'm at it, why not put a little better muffler on there. Any body use this muffler before?

i have a 70 series flowmaster on my camaro with single exhaust inlet/dual outlets. the loundness at idle is close to stock but with deeper mellow sound, but is louder when engine is revving. also increased power from flowmaster

Gotta go with the flowmaster, best muffler out there,of course thats justy opinion.

The little extra noise will be worth the little extra power.

I personally like borla and bassani systems myself they offer a deep mellow tone at idle but sound especially mean at mid-high rpms.

Will never buy flowmasters again......my vote goes to a quieter & more pleasant sounding muffler.....borla

Agreed. I'd go with a generic turbo muffler for now. When a serious system is built for it, then get something good. It's not that Flowmasters aren't of decent quality, I've just grown to truly detest their sound. I realize it's a subjective matter but there are so many better sounding mufflers available. Don't be a lemming.

dynomax super turbos. They have a nice but nearer to stock sound and offer good power bonuses

I'm liking the sounds coming from my $20 Thrush turbos pretty good.
