Customer Review: (see review/s)
  • The quality of this catalytic converter is so poor that it wouldn t even fit on the car. The flange was welded on at the wrong angle causing interference between the cat and the car frame and would not allow the flange to seal. The welds are also so sloppy that the exhaust manifold flange nuts would not even thread on all the way because the weld bead interfered. The aluminized coating is nothing more than a sprayed on paint that easily scuffs off on contact with any other surface and part of it was already missing from shipping. The pipe does not have mandrel bends like oem so the flow is restricted at every bend. Thankfully APW provided no-hassle return so I could purchase a twice cost quality replacement. Buyer beware you get what you pay for with this cat.

Customer Review: (see review/s)
  • Installation into the vehicle was quite difficult. I had to remove almost all of the heat shield I even cut away a portion of it so the first catalytic converter would fit. Once I FINALLY got it mounted and tightened the second catalytic converter was resting on the heat shield further down the exhaust. Customer service was great and I saved a lot of money over OEM but Im not 100% sold on the product.

Customer Review: (see review/s)
  • Purchased Eastern Catalytic Direct Fit R & L Cat systems (header to muffler). Looked good out of box, had a reputable Audi/VW shop do work. VW Header to new flange connection not even close. Reinstalled both pipes twice, one 3 times adding gaskets and using hi-temp silicone. Held for 500 miles or so, now have leaks at exhaust manifold connections. VW/Audi uses a cast flange to fit over a sealing protrusion on exhaust manifold. These cats came with a simple 3-bolt flat flange that will not seal. Also, the right one had welding slag hanging into front O2 sensor port that ruined the O2 sensor on installation (mech was able to remove slag with a long punch, sell me new one). Heat shield on right cat was welded on wrong side - top on one, bottom on the other! Finally, at end of cat system to muffler. right one was 2" too short and angled wrong. Only had 1/8" to connect to clamp, left one was fine. Now I have $1000 in labor and the cats are used. The 3 gaskets and silicone sealed for about a month, now it sounds like a tank and O2 code is going off due to leaks. Don't buy these cheap Eastern Catalytic Cats, buy something better!

  • Replaced entire exhaust and this item was part of it. Couple days for shipping arrived undamaged had everything welded and installed and sounds great. This is a fraction of the cost of a direct fit/bolt on converter so was pretty much a no-brainer.
