That must be a SLP Loud Mouth...

No it has a muffler.

What about the big block muffler to quiet it down?

Then I bet the muffler has been replaced. Also bet a Dual Dual muffler would cure your problem.

No. It's the original muffler that came with the slp catback.

Still no comments on the big block muffler idea.

Why can't you just use one of the bigger block off plates and run more exhaust thru the muffler? That straight thru muffler is real quite and still out flows a stock muffler.

It's very rare someone wants a performance car quiter than a Dual/Dual.

Add a bullet muffler to the I pipe or put cats on it. Maybe find a stock Z28 catback.

If that doesn't make it quiet enough.. well..
