Exhaust and Intake
Improvement of the air flow for my diesel seemed to offer the best bang for the buck to increase power and fuel mileage. So, I purchased a Diamond Eye Performance 4" stainless steel exhaust system complete with down pipe K4307S from Summit Racing. I also purchased an AEM Induction Dryflow air filter AIS-21-3059BF and a Spectre Performance air intake tube 9749. Hopefully, these new parts will improve the air flow.
Removal of the OEM exhaust was easy. I did have to make one cut to allow removal of the tail pipe so it would come over the rear axle. I plan to keep the OEM exhaust parts so I can go back to stock if the need ever arises.
The new parts fit well and were put together with clamps. I made one cut to length to make it fit correctly. I reused the OEM hangers where possible. I did not change out the down pipe since the only difference in this one and the one I recently installed was the new one is stainless steel. I will keep it for future use if the other one ever fails.
Now on to the new air intake.
I removed the OEM air box to make room for the new air filter and intake.
The intake tube I bought fit directly into the OEM intake rubber and allowed direct attachment of the new AEM filter. All that was needed was a support bracket I made out of aluminum strapping and a bolt hole in the end of the filter for attachment. I used stainless steel hardware for the attachment.
I used some poster board to make a template of the bracket and bent the bracket.
The final result turned out nice.
The truck should now be able to breathe.
