Get what you pay for
Welds are decent could've been welded on inner joint of flanges and smoothed out like most quality pipes for smoother flow.. no bolts/nuts came with hardware, gaskets are of ok quality I would definitely buy better ones such as the grimspeed aftermarket gaskets. Sound is good, install was smooth flanges were clean. You get what you pay for. Decent quality fair price overall satisfied went well with plm uel headers
