NO LOWERING.....I agree then..... go 3" .mines 3" and speedbumps are troublesome to say the least.

2.5" inch collector is what will hold back the flow. With the Long Tubes you would be better off with a 3" or even a 3" x 3" ---> 3.5" collector. That would be best. Then 3.5" back to your catback. If going custom, they should be able to tuck it up there nicely, such that it won't hang low. With a ypipe your collector will be the biggest limiting factor in flow.

Ok so how does this look for the y pipe build? Should have everything here besides the mandrel bends, and the clamps. Let me know if I am going 100% in the right direction
Flowmaster Y collector 3 x 4 x17.5
Flowmaster 3 inch to 3 inch ball flange kit (2 pairs)
Flowmaster reducer (Wrong size though) 3 inch to 4 inch
