Best prices on Race Me Ultra

[Sierra1]

I have a buddy bringing his 2015 Cummins in for a tuner and exhaust emissions delete pipe. He's looking for the best deal on both. What authorized vendor sells the Race Me Ultra for the best price? How about a delete pipe that retains the OE downpipe and tailpipe? Is there any reason he should go with the Anarchy tuner over the race me? TIA
