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
Ordered a catalytic converter for my 1995 Impreza on your website. The part itself is high quality but came with a dent (it looks like it was damaged while shipped), so I refused the delivery and called your customer support to replace the part. I got a new one in 3 days. Great service! Thank you!
