Sound is good, must sound pretty mean without cats.

Will the ZL1 NPP work on a 2010 SS L99 without modifying the pipes? I know I will need to add the vacuum system, diffuser, and such. I found a good deal on the NPP pulled from a 2013 ZL1, I just don't want to pull the trigger unless I know it will pop right in.

Yes it will go right in your 2010.

You can get the diffuser for less than $100.00

Here's my L99 with Stainless Power LT's no cats and ZL1 NPP Exhaust with Mild to Wild switch.

Sounds great. I bought a set out of the vendor FS section here and am going to run it with LG headers and no cats. nice to get an idea of what it will sound like
