...anyone tried them? or any opinions on if they would keep our cel off just fine ?

Yep...I use them all the time on customers trucks and cars when removing the cats...

cough-(This is for off road use only...or test purposes)-cough


In all seriousness, I have used many. They work great. They are such a stupid simple idea...I wish I had thought of it...


EDIT: It's the Mini Cat fix that I have used...

good to know cattleac !!! thanks for the input ... i will definitely try these first when i install long tubes - hopefully they keep my ses light off & no need to get the rear 02's tuned out
