'91 ZR1 different Mufflers and Control Arms?

[bradd15]

My apologies if this is a dumb question but I have been looking at 90-92 years and I noticed in the underbody pics of a few '91's some have the rectangle muffler and some have the double pipes on each side.
Also, I see some control arms are black and others are silver.
Was this an option or part of a package or color combo?

Thanks for the information.

Please disregard the control arm question. It seems I was looking at some that were were not as clean as others so what looked like black was dirty silver

All 1990-1995 ZR-1's stock mufflers had double pipes on each side

The older I get the faster I was.

Thanks for the information Mr. Yuck.

Here are pics of a '91 and a '95 with the rectangle muffler outlets.

Sorry, but that is not true. Here is another 95 ZR-1, check toward the end of the video.

All 92-95 ZR-1's had the single rectangular (LT-1) style Semi flat black tip from the factory on each side.
The mufflers themselves on those years ZR-1's were somewhat more restrictive than the LT-1 spec mufflers which disappointingly, had a notably "healthier tone" than the ZR-1 stock muffler.

Yes, that's not stock. Some people liked the LT-1 rectangular look so they replaced the mufflers or added muffler eliminators rectangular.

Not even close. 90/91 quad muffler tips were exclusive to ZR-1,92/95 all Corvettes had same tips.
