Rocky,
I've gotten estimates for around $1,600.
Using the 2.5" aluminized pipe only lowers the costs about $300. The expense is in the labor and custom Mandrel bending.
The system is installed from header flange to bumper with those special clamps, "X" pipe, Custom Stainless mufflers and fully serviceable too. Sounds like everything else on this build. OVER BUDGET!


Common sense, the least common of all the senses.
