Thinking about a exhaust cutout for my 99 SS

![Exclamation](https://ls1tech.com/forums/images/icons/icon4.gif)
I'm currently running all factory exhaust except for a Magnaflow muffler going into a CME. I have considered replacing the Magnaflow with a LM1 but affraid I might get tired of the loud exhaust after a while. Should I just get a electric cutout and place it in the I pipe before it bends and goes over the axel pipe like this?

Has anybody ran into any problem with heat, etc doing it this way?
What size is the factory I pipe on a 99 SS?
Would this be the cheapest and best bang for my buck? ( Don't know if I should have posted a link so Mods please delete the link if I wasn't supposed to put it there
)

Would I need anything else to do the cutout besides what's in the link? Thanks for looking!![Grin](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_grin.gif)

Go with the DMH cutout. I have it and it is awesome, one of my favorite mods. I have it right where it says in that picture and no cats on the car. It gets nice and loud plus it sounds sweeeeet with the cam.
Stock piping I believe is 2.50" someone correct me if I'm wrong

I'd probably stay away from DMH cutouts, the owner/company has alot of negative feedback for not returning or answering phone calls/emails. Im not sure if he is still in business even, your best bet is to go with QTP. Atleast you'll be able to contact them if you have any issues.
Also, I agree with QTP on you'll want/need a turndown to help get the gases out from under the car but I would probably skip buying the wireless remote in my opion. A switch in the car is easy enough to use.

Paid a local shop $70 to weld the Y pipe in for the cutout.

Here was my setup. The I pipe is more like 2.75" OD and I bought a QTP 3" dump and a DMH ecutout. I think I relocated the wiring to another grommet since the location depicted in the picture was exposed to the exhaust. As far as the turn down it is a nice to have and not really necessary.
