It is a resonator, and is straight through design. A friend did that to his 1hz and it droned afterwards at certain revs...make sure you use a flex joint, have you considered extracters?

Will extracters go past this point or dose it still remain after extracters r fitted. :?: :?:

extracters go back to the flange and have their own flexy...

i chopped out that first muffler on mine so i only had the big centre one. not a problem and made only a minor difference in power and not alot in sound.
Although mine was all original.. (2+1/4?)

have just fitted up extractors and full 2+1/2 zorst today (absolute prick of a job) and on mine the only difference is from manifold/extractors > flange right on top of chassis (instead of still in engine bay) and then still have flex joint in next piece, then onto centre muffler etc.

do yourself a favour and get some extractors while your at it, seems as though you already have 2 and half most the way through.

have fun
