I'm ready to install SLP Loudmouth II for my 99 Z28. I want to know that, is one muffler enough or I can instal dual mufflers, which one would be better?

I would think one would be ok. Hold on, let me ask you this, are you running it straight out the back or are you going with turn downs?

z28-99

straight out, right now it has the stock system, so i was thinking to put one on each pipe before the tips,

I would put one on and just replace the factory one. But thats just me and we gotta have cats here in NC so I just replaced my factory muffler with 1 in 2 out.

here in CA cats are required too, I was thinking to put a flowmaster 80 series since it's cheaper and really easy to instal, I'm looking for a super deep tone, like when you have dual original 40 series on a mustang gt. What did you instal on yours?

Do true duals no y pipe and lm bullets

I agree with Skeeter.
