ATS Exhaust Manifold
The product did not "directly fit" into my 2004.5 as I had to tap the right two turbo studs "shoulders" and cut the right front down as it was too long to put the nut back on. Would have been nice to have been suplied the right parts with it or mentioned the possibility of this in the instructions; vice having to get a ride to get a tapping kit or diffenet bolts. Notified ATS and no response; makes you wonder about thier customer service. Other than that great product and will improve gas mileage and lower EGT's.
I had this manifold installed on my '03 Cummins and it was well worth the money that I paid for it. It does help the turbo spool up faster and that helps to smooth out the power band. The truck also sounds more powerful through the exhaust. Overall, well done by ATS.
