Home made 3 inch down pipe

 

I am cheap-I need to be because I am a full time student and I have many other car projects that all need some money spent on them here and there…

 

I decided to build my own 3 inch down pipe to save a little money. I bought two 45 degree 3 inch mandrel bends from J.C.Whitney for around $40. I used about the first 1.5 to 2 inches of a stock dp.

 

Toconnect the 3 inch pipe to the stock pipe I cut 8 small slits in the 3 inch pipe and then bent the “tabs” in so that the inside dia was about the same as the out side dia of the stock pipe. Then I just welded it all together.

 

I also welded a 3” to 3” header reducer (two for $17.99 from Summit racing) to the down pipe and welded the other one to my cutout (also from Summit). This way I can easily take the exhaust off if I need to take the trany out or something.
