i want to order the Cable operated Mr. Gasket's exhaust cutout from summit MRG-5424 for $46.88 its made of cast iron. does anyone have one of these and can tell me how they like it. another thing is i was trying to find more information on if i installed it before the cat on my formula i heard i would mess up the positive perssure egr valve on my 89' 5.0 tbi car cause it to throw codes etc do to not having enough backpressure. so i was woundering if i installed it after the cat would i still have any problems with that?

 

never mind i ended up ordering the regular maunal open style cut out 2.5 inch, but i still need to know if i can place it before the cat and not have to change egr valves or anything like that.

 

anybody want to help me out?

 

You can put it behind the cat no problem. Think about it - the exhaust is just going through a muffler and some pipes after that anyway. It'll be fine.

So you got one with just a plate that you unscrew? good idea. I kinda think the mr. gasket one is a POS. An electric plate can be had for pretty cheap. That's what I have.
