The links below are for the Floored Fab setup only, which is 2.5" collectors. Depending on your size of exhaust, that is what the cutout size should be. Alex, I have driven with them open on the highway for 30 miles non stop. My IATs did not go up or down, but my ECT actually went down slightly. I have been running them for years with no major fluctuation in temps at all. My a/f was monitored on the dyno when I made the gain, and it did not change much at all, not enough that Tony felt the need to adjust it with them open.

Pullejo on here has the exact same setup as me, and we both have been running them the same amount of time. He drives his car a ton, and knowing him, he probably has them open daily, lol.

This is the link for the kit:

Move the cursor at the bottom of the vid to 2:30 for open cutouts (open headers) on the street:

Alextaylor29 this is a good thread cleared up some of my questions still unsure if I will do it or not probably will end up just doing a pulley upgrade

Thanks Chawkins!

I have these... Few facts...

Cutouts are loud, sound like crap... Headers, xpipe...
Lost power with cutouts open. 8whp to be exact.

Thanks. Based on this, I'm going to pass on this mod.

People who have / had cutouts, would you do it again?

I've heard that the seals aren't that great after some time.. exhaust leaks?

Yes! Maybe I've just had bad luck over the years, but the ones I've ran fail after awhile.
