Sounds like that might be a Tundra.
Someone posted this on the TRD Exhaust Owners thread... no one ever addressed it, and it's the first I've heard of it.Can someone set me straight. I have an 06 db cab 2wd sport and I have looked at my stock exhaust. It has 2 cats on each side,before they join to form a single exhaust pipe that goes to the muffler.
I've e-mailed the dealer where I bought my truck to see what kind of deal theywould do. Well not only did he insult me with a 495.00 price for pt #pt910-89061, he told me the TRD exhaust for my 06 is really ptr10-35000-23 (for a dual cat system) for a price of 725.00 plus tax
