Anybody running Open Exhaust?
Anybody running Open Exhaust? Will I have any problems with this setup.
MAC's ported with ball flange cut off.
No Cats
3" Pipe to an x-pipe and turned down in front of the axle true dauls.
Any chance of bending a valve? Or any kind of other damage?
Yes I like it loud.

Re: Anybody running Open Exhaust? That setup should be fine...it will be loud! <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
Running open headers with nothing coming off the collectors is where to start to run into problems...

Re: Anybody running Open Exhaust? I appreciate the info. Down here in Geeeeoooorgia you can get away with alot without offending too many. If it is to loud I get some Flow 1 chambers.

I'm hoping having flowtech cutouts directly after the headers won't be a problem, but we'll see! Its about 8" worth of pipe at the shortest side. 12" is supposed to be the safe bet. I may put a 4" pipe between the cutout and the collector.

Re: Anybody running Open Exhaust? Your car will only run good WOT but i dont believe you will hurt motor from no backpressure. If car stays in open loop you will use lots of gas and will probably dilute oil fast but i am only speculating. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
