Full 4-2-1-2

[jayzee]

Does anyone do an full 4-2-1-2 system for the Gen II with similar performance improvements to a good 4-2-1?

If not what performance difference is there between good slip ons and a full 4-2-1?

(What the best of both worlds performance and twin exhaust look).

Hi

In this kind I went searching.

But for the original exhausts though these are all converted to open.
But I'm the heater to the search of 4-1-2 and the output must be dia.50mm.

See drawing.

ti force make them as well with aperformance header.also you can use a vance and hines header with yoshi slip ons.the vance and hines header with accropovic twin outlet dual mufflers is supposed to work well and produce very good hp and torque,the headers are stainless

I am running them on street and strip The best exhaust system in my opinion produces propably the most power of any system and has a deep rumbly tone also only weighs 6 kg against the oem 23kg
i got a 16 hp increase when i put them on. run before and after install
184hp to 200hp at the back wheel
