Exhaust chamber

it doesn't look bad for the price ,,has the proper shape exhaust port ,,some have a circular port which is restricting the flow ,i have one i bought from bikeberry paid about 20 more,,but its chrome ,,cheap chiness chrome ,,but it works fine ,,if your running a grubee ,,pirate cycles have a high compression billet head ,,i put one on my GT-5 ,,what a difference ,,and it took 5min. to put on ,and i was riding in 6 mins.well worth the money 60.00

These are sometimes loud enough to bring unwanted attention, and sometimes require a change of main jet in carb, but price looks good.
