What do you mean sneaky?

I ran a hooker aero chamber and a Berkeley straight through at the rear. Was under the legal vole by a fair bit, no drone and flowed over 300 rwkw.

Research exhaust design. Two mufflers the same don't do much more than one. Fit the biggest mufflers you can fit. Look at branch resonators if you have a particular frequency drone you want to cancel.

I tried a few combos until I was happy with the result.

whats the biggest size mid or center muffler that can be use and still have 100mm ground clearance?

That exhaust system in the pics looks identical to what I have, but mines 3 1/2inch and a 3inch large oval Xforce muffler on back and is perfect, sounds quiet enough and on boost nice...

the muffler I have snakes inside the muffler and works great.

heres a brief clip, pretty quiet, got loose in first 3 gears lol

I have a magnaflow VT muffler on custom full system. Louder than stock obviously, but very easy to live with around town and it opens up when I sink the foot in. youtube it for examples

I can supply either a 3" or 3.5" muffler / resonator combo without any stepdowns that have max flow and a deep , quieter sound. AES is the name. If you want to go quieter check out active kits at www.activeexhaustsystems.com.au

Fujitsumo twin 2.5" is reasonably quiet. Not that you can buy it new anymore. Because it is twin 2.5" it has good ground clearance.

I've had one on the car 7 years and police pull me over probably 10 times in that period, at least. Only comment I have had from them on exhaust is that it sounds "reasonable".
