We are the only fabricator that will remanufacture Cummins marine exhaust elbows and marine exhaust risers and then warranty the work for 5 years.  Your elbow or riser will be rebuilt not just repaired.  The materials we use are 316L stainless steel and are nearly double the thickness of the new replacement parts.  If you have a Cummins 4BT, 6BT, 6BTA or a 6CT then we can probably remanufacture your exhaust elbow or exhaust riser and save you hundreds of dollars and be far better than when it was new.  Our optional ceramic coating process can greatly increase the service life!  Be sure to ask about it when you call.
