here are some pics of a new product we just finished for the Cougar. This pipe will only work on 3-bolt flange cars. we have not had a chance to check out the 2 bolt flange pattern yet...
with this part, you will be able to either eliminate your main cat, or use our high-flow cat version. this part was made to be used with factory or MSDS headers. (truth be told... we made it with MSDS header use in mind).
check out the pics below.
the part is all mandral bent in 2.5 inch tubing, and has 3/8 inch flanges. prices for the aluminized unit will run $70.00 without the cat, and $125.00 with high flow cat.
