Here's a pic. The diameter looks to be exactly the same as the rest of the pipes.

I replaced resonators with straight pipes on my GT350. The diameter of straight pipes on R is 2.75".

No dronning. The guy who own muffler shop cut off resonators and welded straight pipes for $160 out the door.

Are you sure its 2 3/4in? I just left a muffler shop and gentlemen said that's a very odd size, they would have to check to see if they can get a piece of that in stainless. Was it a 3 inch pipe they reduced at the tips to fit? He was trying to talk me into replacing my entire exhaust, maybe he didn't want to be bothered with a small job..

Were they able to reuse heatshield?

You may double check on the pipe size. No heat shields needed and I don’t have them on my. Make sure this guy can do good welding job. You don’t want hole in the exhaust.

Any idea why the R has a heat shield, but when everyone does a delete they say it isn't needed?

IMO, there's nothing to protect from heat. On the sides there's already heat protected material and between top and pipes there's a drive shaft and a lot of room for heet to evacuate. Also, those heat protectors on the top of the pipes are so thin and short, not sure why they on there to begin with.
