Arrow McCord vs. DMH cutouts?

hello all, i don't post much on here, but i need some opinions. i have been searching for anything electric cutout related for a while now and i have it narrowed down to the McCord power plate or the DMH. The obvious choice for most would be the DMH, and i definitely do like the 4 year warranty it comes with. the McCord offers a 1 year warranty.
this will be installed in the I-pipe, on an otherwise stock exhaust system. this means i am looking for a 3" setup, correct? i have found conflicting information when it comes to that. some people say get 3" for stock exhaust and others have said 3" will require reducers. can anybody clear this up for me?
i have been at this for weeks and i really just need some guidance on which one to go with.. its also 129 for the McCord and 179 for the DMH...both without the cutout y pipe. i will be running a turn down on either one i get, but for now i'm just looking for opinions.
Thank you very much in advance.

The BEST I have seen is the NoWeeds diverter... I went with the DMH for my RS with Borla adjustable cat-back, but NoWeeds is going on my SS w/SLP Dual-Dual...

DHM, it has a 4-year warranty. Im curious about the NoWeeds diverter. Saw the website but looks like the design more complicated compared to a regular "straight-shot" cut-out. Just wonder how the mechanical components work.

thanks for the replies. the NoWeeds diverter is a little more than i'm wanting to spend on a cutout. there's certain things about the McCord that i like, like the welded butterfly valve. since i'm in school, i also like the price a little better, but i'd be willing to spend the extra money to do it right.

can anybody verify that the 3" will work with the stock I-pipe? i want it to be a 'cut, slip over, and weld' deal.. i don't want to mess with reducers.

also, does anybody here run a turn down on their cutout? i want a deeper sound and i think this is the way to get it from what i have read..i just haven't actually heard anybody with that setup.

thanks again.

That noweeds thing is ridiculously over-engineered. Plus finding room for that expensive monstrosity under an f body would be very difficult. I say pick the one with the longer warranty simply bc e-cutouts have a bad rep for acting up, going out, rattling etc.

NoWeeds is supposedly the only double butterfly system, and a straight through "h" design...

Does anyone like the sounds of dual e-cutouts on the Y-pipe, as opposed to a single on the I-pipe on a 4th Gen? (the pic above is a 5th Gen.)

Also, the actuators used on NoWeeds are Dakota Digital which warranties them for a lifetime:

I had a QTP one and if I decide to replace it I would go with a DMH

i have pretty much ruled out QTP after reading all the negative reviews on here about them. i realize they all have problems, but it seems like more people have had issues with them. probably just a result of more being sold. another one i have been looking at is the badlanzHPE. it offers a 5 year warranty and you can buy all the parts separate.

does anybody know if the DMH will stop moving when its fully open or closed? i hear that many of the cutouts die from the button being held too long.

also, after some more reading it seems that the stock I-pipe is 2.75"D. will a 3" y pipe mount up to that okay?

Just as 01ssreda4 said, NoWeeds looks way over engineered. IMO just looks like a more flashy way to take care of a simple concept. Over engineering can be a major design flaw.

Keep it simple and you'll have less problems with it.

That pic of the noweeds isnt an f-body, it looks more for flash rather then function. For a show-car, it would look good.

If you're worried about possible failure, you might be interested in a Race Ready cutout. They come with a lifetime warranty.

NoWeeds uses off-the-shelf electronic parts:

That was a reply to the "over-engineered" commentary...

You can engineer something from off-the-shelf parts. Over-engineering something is just making/designing something more complicated than it "should" be.
