I did replace the exhaust manifold due to excess expansion, pretty common I understand, caused it to whistle when exh brake was applied. Pac Brake replaced the CHINEESE compressor with one built in Canada, been great since. Never could understand why they would build a quality exhaust brake and use a junk Chineese compressor.
They sell the cheap one that has less of a duty cycle. The 100% duty cycle is much mote $$$.
They replaced mine also.
