Theory

Ok, curious

I consider myself a "car guy" but certainly no engineer.

Given that I dislike the 4cyl sound, I refuse to get a "fart can" muffler for my car. I'd prefer that she's as silent as possible, but don't want to sacrifice the gains of a free-flowing exhaust.

My question is this: Dual exhaust? If I want silent mufflers, would adding dual exhaust (after the cat) negate the backpressure from the type of muffler/resonator that I'm looking for?

I've done some research on the subject here, and the general concensus seems to be that dual exhaust is pointless aside from looks, but no one has broached the subject of a restrictive muffler design as part of the concept.

Thoughts?

+1 on the Stealth kit.

Doesn't sound like a "fart can", gives moar powah, and is quite quiet.

I'll probably go with that, then, if for no other reason than to take any guess work out of the build.

On a secondary note, however... Is the theory sound? Or am I making up imaginary and erronious solutions?

I have a 2.5" Borla with zero rice sound. It grumbles when rpms slow down, it's awesome. In the morning when it's colder, it drones a bit and annoys my neighbors so I may go with an added muffler, which would basically be the same layout then as the FSWerks stealth.

It sounds as if the FSWerks Stealth will be my best bet.

Still, is there anyone out there that can tell me if splitting the exhaust after the cat, doing a dual exhaust that way would negate the backpressure of a typical "silent" muffler?
