I just went out to look at my turbo and exhaust, so I stand corrected..... I have a stock down pipe to a $inch after market exhaust, NOT a TB 4inch system

I dont know if its an 03 or 04 motor, how can I tell without being a major motor head? What difference does it make for the years on the motor?

03's have the bad **** turbo whistle others don't , early 04's had 03 motors . Does yours have the catlitic convertor still in place? They don't get loud till the cats gone.

There is a sticker on passenger side valve cover that has horse power and torque ratings and i think build date. But if you got that loud whistle probably 03

Checked the motor, and found the valve cover, it is an 04 motor, I think the guy who had it before me did an egr delete, states that the motor has 325 hp stock, and 560 ftlbs torque. This truc has a K+N air filter also.

What would be your suggestion if it was your truck, to keep the 4inch exhaust or go with a 4 inch straight pipe?

I was told that if it has a glass pack, which I think it does, it wont be much louder, and I checked for that CAT, and I dont see anything on the pipe, not even at the turn of the pipe.
