  • all it came out to be a really great product. I wouldn’t hesitate to buy it again.
Size: 3''Straight+45°+90°+180°-8PCS
The media could not be loaded. Well it seems very thin and not very round and very dirty on the inside. I will try and make it work and update this later .UPDATE I actually really like this piping. It did the job at first you can tell. I was very skeptical because of the odd shapes, but it didn’t really affect anything. All in all, it’s a great product and I got it on Amazon warehouse used deal for a little money also, the thickness is what the advertise so please retract my previous statement of it being thin thank you off. ... show more

  • Decent diy thin gauge exhaust
Size: 4''Straight+45°+90°-3PCS
Not consistent diameter all the way thru. A lot of out of round, still workable. It seems like decent quality ss though. Used it for a downpipe on a turbo set up where I needed to pie cut the straight pipe, cut the 90 in a couple spots.

  • Good quality 3" tubing
Size: 3''Straight+45°+90°-3PCS
Great price and the tubing seems to weld nicely. It's the perfect thickness for an exhaust or turbo kit.

  • Pretty good value, definitely convenient
Size: 2''Straight+45°+90°+180°-4PCS
My minivan was much too quiet for the trackday and backroad weapon it truly is, so i did some searching for 2” diameter tubing i could easily clamp in place to the stock system for a muffler delete. Honestly i’ve never done exhaust work before and was expecting to have to make pie cuts, splurge for a tig welder, hire an army of professionals, the like, but it was honestly way too easy. The piping cut nice and easy with my anger grinder & cut off wheel and is actually thick decent stainless steel. One of the ends which i cut off anyway was very very slightly crushed or crimped a bit on the end, but nothing you couldn’t persuade with a hammer. Overall solid tubing if you can’t find any locally. With that stock muffler gone i’m officially prepped for thousands of HP and regularly get thumbs up from passersby and S2000 owners. Six thumbs up! ... show more
