Flashark - Reviews and experiences

A rainy afternoon and a link from a buddy started this. He recommended it, said it fit his rig. I ordered and it arrived after about a week. It sat on the bench until a sunny weekend. The piece itself felt nice — decent heft, clean welds, no weird burrs. But install? The bolt holes don't meet the block. A couple of centimetres off, which is maddening. I bought it for my exact engine code. Took it to my local shop just to be sure; they confirmed the flange was out. Returns are only for unopened parts, so I'm left holding a heavy paperweight. Bit of a waste. I'm annoyed more than angry. I'll tell friends to be careful. Good material, bad measurements. Not ordering from them again. Wish they'd checked specs better already.

email back-and-forth that feels canned, slow replies (a day or two), no phone number, and the last message was just "sorry it didn't fit" with no offer of refund or solution. I've had better luck with other shops locally, but hey, at least the part arrived. Could be handled much better.

no instructions (but it was assembled so you kind of figure it out), and one side has that slip-on section with a clamp which felt odd at first — fit was fine though. I told a coworker about it already. Mildly surprised and pretty glad it worked out, would recommend to another Altima owner.

the pieces are heavy, the metal feels solid, welds look decent, and the muffler gives a deeper sound right away — not tinny, more like it has some weight to it. Installation wasn’t pretty. I had to trim the main pipe by about six inches to get a decent fit, which I’d suspected I might need to do, so that wasn’t a surprise. What annoyed me more was the hanger tab hole: it was almost a full hole’s width off from the corresponding piece, so no way to bolt them together without force. I tried pushing, prying, re-aligning — no luck. Ended up fabricating a hanger from an old bracket and a spare clamp; ugly, but solid now. Once it was on, the system feels rigid, no weird vibrations, and it sounds right when you drive — deeper at idle, stronger on acceleration, not obnoxious. Support answered my email but just sent a link to a YouTube install video, after I’d already finished, so service was okay but not helpful at the moment I needed it. Overall I’m glad I swapped it, mainly for the reliability and the way it drives now. Slightly annoyed by the fitment and lack of paperwork, but satisfied in the end.
