catalytic converter performance 850

you can get a 3" downpipe with race cat, they are $$$ but might benefit some, although unless you have a highly modded engine and free flow cat back exhaust system changing or removing the cat may not be a great improvement in HP or MPG because of the resrtictive volvo muffler. it is best to do exhaust mods from the rear first and the cat last.
