So, all the people out there who have long tube headers have either had to buy new y-pipes or modify your y-pipe yourself either keeping the stock cats or getting an off road y-pipe. So, for the people who are just buy straight LT headers and keeping your stock cats, how hard is it to modify that?

 

I had a custom shop add flanges to the ends of the collectors, reroute the stock cats, extend the O2 sensor wires and custom fab all the pipes.

 

wow, how much did that cost you?

 

Pacesetter coated LT headers, dual Mag 6" round mufflers, Mag x pipe, Mag tips, 3" pipe, all labor, total install = $1600
But, compared to what I would have paid for a set of Dynatech headers alone, my set up isn't expensive at all.

Good luck with yours.
