I have an opportunity tomorow to run my car open header tomorow night at the drags because I do not have my Y pipe back yet. Has anybody else run open header before? I know my ECU lights are gonna be screamin at me, but I think it'll be in good fun. And see if no exhaust helps/hurts the times any.

 

Do it, and post the results!!

 

get some earplugs. it's real ****** loud.

 

Adam (My4DSC) ran with a dump tube, daaaamn that was loud.
He only got one run in before they kicked him off the track (mufflers required that day)

 

wow, I've heard about someone else doing that. I was wondering if you lose any backpressure from doing that?
