I’m a DIYer who broke the rusted bolt when trying to take off the old cat, fortunately, it was the only problem I faced, the cat is direct fit and high quality, came with a gasket, you may also need an anti-seize lubricant and new downstream sensor, the old is really hard to remove without breaking
a good quality converter with a direct fit, not sure if it adds power but the sound is better now but maybe because I replaced the muffler as well, no problems during installation… the latter was a headache when installing the previous converter
noticed your “pre-fit” in the name of the part, so did a couple of checks before assembling the cat, but the fit was oem, the converter is very high quality and sounds much better than the stock one, recommend it in tandem with a magnaflow cat back for the best sound and performance
talked to your sales rep, who recommended the magnaflow catalytic converter for my son’s toyota. The part was delivered in two business days which was a big surprise for me. Thank you, guys! I’m gonna do business with you again!
