where's the Cheetos?

 

i was just saying why pay for a muffler with a straight thru design if the sound will be the same as or very close to having straights... thats the point i was trying to make..

 

Straights are not my taste!

 

well thats fine. everyone has a right to an opinion..

 

^ And I'm not afraid to voice it!

 

Well I have mine off for TODAY only. Just ran out of time to finish it up. Bought a magnaflow 2.5.
Hope it sounds better than today. Being so loud is very annoying.

Most people seem to punch it all the time with the straight pipes and look very stupid.

 

Because even the straight thru muffler by design effects flow and volicity. It's a complete system. You may run a little leaner without, but it's more of a noise nuisance. To lean and you can burn the valves. The valves do take a hit; how hard ? It depends how lean you are @ cruising speeds. There's an explanation here ~

I'm willing to bet if you ran a quarter mile with stock exhaust you would have a better et than with straights

 

There are so many Dyno proven fallacies in this thread I don't know where to start so I won't

Having SIDO straight 2 1/2" from the trans case back into 4" tips on my 07 was a pleasantry, Not obnoxious just a deep mellow rumble. My 2010 is a different story as they now come with different manifolds and only 2 Cats instead of four, Straight pipes on the 10 produced the horrible 1 7/8" straight piped small block welfare engine (350 chevy) sound that we all have heard and can not tolerate. However after adding the pro flow Louvered Core glass pack muffler it sounds perfect. My .2

 

When running proper AFR at WOT, you will have some crackling sound in a high performance exhaust due to some of the flame still burning when the exhaust hits your manifold/headers. At least on the '09 - '10, the stock tune on the 5.4 holds the AFR at 14.7:1 until 4500 RPM (which is silly IMO). If you run a more reasonable WOT AFR (10:1 - 12:1), you will have more power and more noise.
