Question about 2007 Toyota Yaris
I love my Vitz / Yaris in every way, shape, handling, feel, facilities, economy etc. There is ONE loud snag only. Its engine 'roars', and I found it has 3 cylinders, compared to 4 cylinders on older Vitz 990cc. The noise and vibrations coupled together are irritating me. A friend had an extra MUFLER installed; the workshop I go to recommend removing Catalytic Converter and installation of a mufler instead. They say this will improve pick up, which is not bad already. Its just the noise, which is like a 'diesel' car. Please help or comment.
recommend headers, with 2 1/2 inch true duel pipes, feed it to an aftermarket
cat, a must have, with all O2 sensors, then run Your pipes into some cherry
bomb glasspacks, then run it out to either comming out just in front of or
just behind the tires, with a turndown right before the quarterpanel wall.

NO, a cat only cleans up pollutants. It has no effect on engine performance unless you have a misfire and the cat works overtime and melts and cloggs the exhaust system. If your blowing grey smoke out the tailpipe then you indeed may have a bad engine. What I would want to know from the mechanic is what is the compression and why he thinks its a lower engine issue rather than a leaking valve on the head which would be alot less expensive to repair. Then again you could get a second opinion from another shop. Mechanic shops are known for gouging customers wallets, Not that i'm implying anything here.
