Can't understand why I didn't think of it sooner. I have laid an old bedspread in the boot and it has reduced the exhaust drone considerably.

Mufflers work well too.

i believe the stock rear mufflers produce a drone in the rear at a particular rpm and speed range, in the v8's

the plastic spare tyre carrier dosnt help the situation

wow, i would go for a better zorst with better quallity mufflers, I have a 3inch, super super high flow cat, and a staight throught 3 inch muffler at the back where the resonator should be. No drone here, but that might be from the turbo.

yeah, turbo's are pretty good at drowning out exhaust noise, but a mattress is cheaper :whistling HAHA j/p

Where do people get mattress from bedspread?

The noise has been lessened by insulation, you haven't solved the problem of the drone.

The wrong exhaust on an alloytec equals drone.
