Those are Rush mufflers.

 

I'm gonna go with stock headers, se buckshot heat shields and rush slips.

 

They are Rush slip-on mufflers. I recommend using the baffles. Performance should drastically improve with them in and bring the volume down to a normal level. PM me your email and I can send instructions for installing them. The front cup on the baffle needs to be spread open. When installing you have to tap it into place to compress the front baffle cup into the front of the muffler shell. This will seat the muffler so it won't be loose and rattle.

Now that that is answered..I have the same question.

What V&H exhaust is this in my sig?

 

I appreciate you replying to this thread, can you tell what size baffles I have? Also do you happen to have a map for these mufflers with SE AC?

Thank you all for replying to this thread as well and helping me ID these pipes!

 

It's hard to tell without measuring. The best way to determine is to measure the outside diameter of the spiral core section under the baffle matting. It should be 1.75", 2.00" or 2.25". 2.00" is the most popular so there is a good chance it's that size.
