Question Anyone know the length of the MAC ORP, or MAC High Flow cat?

I would like to get my carsound highflow cat welded up with the end flanges before I do the MAC '94-'95 header install. I see that you can buy a MAC ORP or MAC high flow cat that will bolt right up.

If I could find out the length of either of those, I could get my carsound cat welded up with the correct flanges to the length I need.

Can anyone help me out? I would hate to get the headers and Hooker catback installed just so I could measure the gap for the cat, and then make a seperate trip to the muffler shop to get it welded. I'd like to have everything ready.

Thanks in advance,
Dan

I just ordered a mac high flow cat and I was hoping on having it for install this weekend, and I currently have the mac orp on there right now. I could measure both for you when I get it.

Actually, tomorrow I could probably measure it just for the hell of it. I have some other things I'll be doing to the car anyways. But if somebody already knows, please post it.

That would be great. It would save me a ton of time. I thought it would be a long shot to get a response from someone. Thanks for going through the trouble.

Can you get the ORP or cat end to end measurement with it installed?

Sorry about not getting that done for you yesterday, If I can, I'll pull my car into work after closing and take measurements for you.

Once again, sorry

I'm just glad that you're willing to check it for me. You don't have to go out of your way just for me.

Thanks!
Dan
