are there other sizes for down pipes other than 3". I know that there are none bigger than 3", but what about smaller? Im trying to figure out if my supra has a down pipe. It doesnt seem to be a 3" pipe though, but it has a cat-back. The car also has a boost controller, but no boost gauge. any help would be greatly appreciated, if anyone has a pic of a cat, or downpipe on their car that wouldnt mind showing me, it would be a great help!

thanks.

Does your car still have the Cats? If you don't know what they look like go to this sitehere. Hope this helps.

3 inch downpipes are the norm that most people upgrade to. Anything less would be close to the restriction of the stocker. Downpipes are most certainly available larger than 3 inches. A little searching will find 3.5" and 4" downpipes to choose from. These are only necessary on high horsepower supras (650+hp).

I have a tanabe 4" downpipe stainless steel. It eliminates the cat however

Look under the car for the two cans one going to the turbo manifold and one going to the cat back. They are highly restrictive! Tanabe I believe makes the biggest downpipe but can't go wrong with the rod millen dp.

no matter how much chaos life bings me just knowing I've got 285/30's is very theraputic.

You may want to try this, it offers a fantastic HP increase, more than I have seen on any other downpipe.
