Dave, awesome! My biggest deterrent to driving the beast is the unbearable loudness, I found them at summit and amazon ,just curious How are they attached at the header end? Pictures? , thanks, Karl

I had to fab my own 4" elbow-to-flange in order to mate with the 4-hole header flange.

New 'loud' inserts came today- put one on the driver-side. Passenger-side has reverse-flow inserts.

Pics with dB app photos- ignore the min/max/ave values as the were recorded during a walk-around of the car.

I'll try some 0-60 runs this weekend with my dragy- both types of pipes.

Ok, got the 3rd set of inserts- glasspacks, perforated tube (not louvered).

87 dB at idle.

So dBs roughly, at idle:

92 - max-flow perforated tube
87 - glasspack perforated tube
84 - reverse-flow

What's important to me is the ability to swap the cores out easily for different driving 'events' or depending on which 'community outreach' program I'm doing.

I'll get some 0-60 times as well as drive-by video as soon as I can.

MauiKarl,

There are some solutions that come to mind - Boig Quietpipes for one.

You might look at those.

What was key to me is the ability to swap the cores.

These are Doug's 4" Corvette side-pipes with reverse-flow insert/baffles.

Finally I can drive the car without earplugs...

Max-flow inserts come later.
