Exhaust system HZ sandy

[Frosty]

I asked the same question on this forum for my HZ 253 and ended up with extractors, twin 2 inch stainless pipes, no balancer and Lucky Glass mufflers. Sounds mean at low revs and gets loud after 3000 RPM. It does get too loud to hear the sterio after 90 kph (only 1100w amplifier) but I think that all vans do drum at speed? I just drive slower to enjoy the noise.

A balance or X pipe will help reduce the drone at 2500 to 3000 rpm and also reduce noise output at higher rpm and Ive always thought ute and van twin systems sounded a bit off because they are usually diferent lengths because of the fuel tank. The X pipe seems to sort that out somewhat.
As for power and noise reduction a single 2.5 with a couple of offset glass packs will feel snappier keep the neighbor's happy and still have a note.
Its only my opinion but I prefer a single system.
