I was told to replace the cat because the check engine light was on, bought the magnaflow, it’s not the cheapest one but is stainless steel so should not rust like the one I had, fit was good but had to do some piping work
I have these front and rear stabilizer bars from Nolathane On my 2008 Subaru Impreza WRX for about six months now they really tightened up that front end and the body roll is much don’t feel it moving right and left anymore. In the turns I would recommend highly company makes whiteline also in the same factory. So check them out
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
The part looks and fits the same as provided on the website, so it seems to be high-quality. Besides, it’s great to know it is covered with a limited lifetime warranty, so I hope it will live the life of my 2003 passat, professional installation is a must.
