Which one of these will fit my stock exhaust pipes (95 z28) ?


HOK-21729 - Inlet Single, 3 in. center inlet
Outlet Dual, 2 1/2 in. center outlets

HOK-21721 - Inlet Single, 2 1/2 in. center inlet
Outlet Dual, 2 1/4 in. center outlets



the 2nd one, right? I don't want to get the muffler that wont fit my exhaust pipes.......

 

I think the stock outlet sizes are 2 3/4

 

Stock inlet is 2 3/4. Stock outlets are 2 1/4

 

so which muffler would work best for my stock pipes?
