Had my xpipe off this weekend after I installed a new flywheel. i gave my neighbors a wake up call down the street at 8 am yesterday morning! ohh, btw, open lt's or stocks on a v6 are a big no no. I wouldn't even put any louder than stock muffler on a sixxer. Go for the sleeper look and sound.

You only really feel a gain with that on a larger engine or one with forced induction. If you're still N/A, then open headers is more/less for intimidation only.

I ran open headers on my six IMO the idle didn’t sound to bad but when you got on the gas it wasn’t so nice. And I will say that it did seam to feel like it had a little less power then with a full exhaust.

I had to run open headers due to my freakin cat breaking off my header, and white is right. It doesnt sound bad at idle, but getting on the gas is a different story. And it isnt legal anyways.

You will definitly notice a lose of low end power.

One of my friends had a 86 Chevy pick up with a built 454 in it and custom hooker open headers. Now that was just fucking bad ass.
