Except the resonator offers NO RESTRICTION.

If you can honestly question yourself like that, the answer is most likely you are not crazy.

However, you probably are imagining the mpg improvement. This is the time of year when most everyone’s mpg increases significantly. Although there are a dozens of factors involved in real life mpgs the big ones (that change with the season) are ambient temperature, road conditions and summer gas. Basically a warm engine is an efficient engine, pushing an inch of snow/water out of your way takes energy, and summer gas has a slightly higher btu content. Regardless, our PCMs “tune” the engine like every 50-ish miles so any resets don’t have a lasting effect.

And this whole exhaust thing is way too funny. I’ll throw this in just for something to stir the pot, the most significant factor in an exhaust system is its scavenging ability.

Backpressure and scavenging are two different concepts.

its funny and annoying, want me to cut my res in half to prove that its straight through, and has expansion chambers to muff the noise.

L36pro get off your high horse, and come down to reality

yea back pressure is for dd and street cars and scavenging is for racing motors
but there meaning the same thing just to different names

you want a cookie then?

No, they are not.

Exhaust scavenging happens in every car. The perfect form of exhaust scanvenging has the exhaust flow match the intake flow. The exhaust should almost suck the engine exhaust out, instead of it being pushed out.

Backpressure is and always will be a myth.

Potato in exhaust = instant back pressure.

hmm maybe every 100Lbs out is a .1 of second off your quarter time

your dumb

Fail at math?

.1 for 100 lbs means .003 for 3 lbs.
