Im looking to order a hooker cat back system but I need to make sure its the correct part. The description says 83-85 305HO which Im assuming would be L69. I think they use the same 4 bolt cat that is on the 85 LB9 but I need to make sure before I order it. Does anyone know if Im right because the other option is 86+ 305tpi, but I think that is the wrong part.
thanks for your help

 

I have an 85 tpi and yes the 82-85 has an oval reducer (4bolt) on it and the 86+ is a 3 inch straight through. I decided to go with the 86+ but had to buy a 3 inch cat and new y-pipe/headers.

 

cool, just making sure. It would suck to get the wrong part.
thanks
