    "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." posted by: on May 18, 2014

    "i bought both left and right side. passenger side was installed with no problem. driver side though was a real headache. it wouldn't fit correctly. I ordered another one from different company (same part number) and it was the same problem (actualy this time it was even worse). I don't know what is with Bosal i thought that they were making quality parts. at the end i have to cut, adjust properly and weld it back. Wrote to Bosal, still no response... In future i'll try to avoid BOSAL" posted by: KK on January 10, 2011
