It could be as simple as improper rubber mounting was used or improper installation.
The cat converter quite heavy.normally have 2 mounting/ear left right.if no rubber mounting was used the engine vibration transfered exessively to exhaust and to the chasis.ask shop to included some free play or better mouting.
Last time I experience too tight of rubber mounting bracket at exhaust.the vibration translate to chasis vibration.after put some free play ,chasis vibration improved.

actually, if you insist to have performance system to be install in your neo... but you wish to reduce noise, just stick to 1 middle bullet and get a rear muffler instead, throw out the bullet as muffler at the rear, because it will do no good if you keep installing /addon bullet

soemthing like this will make do you good...


I always really hope exhaust guy will start learn the proper to setup proper exhaust, in professional manner, not to just earn money.
the sound you mention probably just some poor workmanship as bullet from my experience hardly will have product defect... because is such a simple product...
hmm that means i have to buy new rear exhaust that are good in performance and low noise..:bawling:

after a long time, today i taken my car to the exhaust shop and ask the mech to fix the problem.i spend about rm400 to cut down all the middle bullet and make a new setup. i also ask the mech to do the straight piping because all three bullet length consume most all the place and not enough to do the s piping. the sound abit quiet and for driving about 100km/h the humming a bit loud. maybe i have to abandon the straight rear bullet with somthing quiet bullet...for all zthian how give opinion and advice to me.. i humbly says THANK YOU :biggrin: for the help...
