BTW nice model. Tamiya? And your rear tires are mounted backwards.

LOL Yeah thanks. It's a Tamiya. Great Model I have three of them cause of the Detail, but nothing compares to the Little Engine I was planning to put in there.

But back to the Subject at hand. What about a OBD2 Spec High Flow Cat from an after market company? I know there is one that will make a custom length. Sorry I can't remember the name of the place but I think it is this one http://store.hybridgarage.com/store/...o=001-01-00001
