Dago, it depends where in your power band you want your power to be. Mid to upper, go with a 3" or if you want it a little more towards the mid range go with a 2 1/2'
Your engine isn't moving water, its moving very hot expanding gasses. You want to have the maximum velocity through your exhaust system with the minimum backpressure possible. An exhaust system with too large pipe diameter will get a reduced flow velocity of the exhaust gasses. The flow velocity of the exhaust gasses assists with scavenging. This is because the flow velocity of the exhaust creates a low pressure immediately behind it that sucks more gasses out of the combustion chamber.
My GMC C3500HD (454 Vortec) came with two 3'' pipes going into the factory muffler, and then just one 3'' pipe coming out the back. I had a muffler shop replace the muffler with a straight-through Holley FlowMonster (PART# 12599-FM) with two 3'' inlets and two 3'' outlets. Not sure if I lost any torque but it sure does sound better!
That trick for cutting rubber hose is pure genius!
"as seen on speed" ooh hit me right in the nostalgia
I have a 4.3 and I ran 3 inch to a magnoflow and too 2/25 out sounds great nice low grunt and a full glass wow sounds great
Literally just got my exhaust done a couple days ago and got two 5x24 inch tips and this came up on my recommendation

Love that cutting block! I wonder if it would work as well with stiffer hose though
I use that method to split my blunts
The size pipes determines on power to the GROUND or at the CRANK?
Great show Man thanks
My truck has stock 3 inch piping 6.8l v10, I'm stick to 3 inch at 325+ horse
Ha! Great tip this episode, definitely one I'll use.
now that's crazy cool!!! 😎👍
ok I have a 2006 v6 2.71 charger and I want to add dual exhaust to it would I lose performance by added this to my vehicle ?
thats awesome stacey,Im thinking to install some shorty headers and x pipe exhaust.
what about a Renault 1397cc 55hp?
What about 3" straight exhaust to a 5" stack out the top. Would that torque???
Stacey I have a 1992 ford explorer can you explain on a show what can it be done with it to have more performance and economy please
