Too Loud

[Ant]

We are about to get a decibel test here in NZ probably about 90DB measured 0.5 M away from tailpipe, this is going to be a problem for my engine, so heres what I intend on doing,

Fit an auger/three disc chambered baffle into the tail pipe, they are easy to fit into 3" or 3.5" curved tailpipes, but the insert baffle can only be probably max of 8" long total, and can be made to fit around the curve pending shape - anything is possible, even if you use three big washers and have the gas into the center of the first one out a cut out in the through pipe then through a series of holes in the next washer, and then back through a cutout in pipe and through center of the exit washer. This works motorcyle guys have them and I used it in my first Cobra, and for obvious reasons it doesnt help performance!

As I am going to probably use more than one exhaust pipe per side underneath the car it will be harder to fit a baffle but I guess its all relative.

Under floor systems, face the exit downwards and slightly inwards to center of car.

Have a 3000 chip in your MSD so they cant rev your engine to the required 4000rpm when you get pulled over, I have an adjustable dial type MSD which will be in easy access while driving.

Drive really quietly around town and let them get used to you, as I only live in a small town that may work.
