I just got a 2001 2500 D/A ext cab, long bed and I am looking into exhausts and air filter kits to start off with. Im thinking about a 4" exhuast with a 5" tip. I would like to lower my EGT's but I want an exhaust that will be louder than my neighbor's powerjoke with 4" straight pipes. I have researched alot on air filter kits but I am not sure what is the best air filter for performance.


Any information will be helpful!


Thankshttp://www.dieselplace.com/forum/smileys/Approve.gif

Banks 4" monster exhuast was evey easy to install sounds great but will not be near as loud as straight pipe. Did lower EGT's and turbo spools up faster. haven't done the air intake yet but am going to get the AFE stage II soon.

AFE Stage II, and 4" straight pipe, 5"x22" S/S tip. That's what I have on my truck. I can't say for sure if it is louder than a PSD, but it is loud! Very loud!http://www.dieselplace.com/forum/smileys/Big Smile.gif

How Loud? Cummins 5" straight pipe loud? Does it have a Deep growl or a farting sound like the Powerstrokes.

DMAX2134- Check out the DPP exhaust systems. You can choose from Aluminized, T-409 Stainless, and T-304 Stainless. The fit and finish of the systems is second to none. Very high quality systems.


AFE Stage II seems to be the favorite or at least what we sell the most of. With the PG7 filter media, it is a tough combo to beat.


Let me know if we can help you with anything.

DMAX2134,


We can help you for sure with this problem, "I want an exhaust that will be louder than my neighbor's powerjoke with 4" straight pipes." We offer our systems with an optional muffler delete pipe that slips in place of the muffler at your descretion!!!!


Being one of the largest MBRP exhaust distributors we have the systems are available in aluminized, T-409 and T-304 stainless steel. The 409 systems come with a 304 muffler and 304 welded hangers, we know that if you're going to have a corrosion problem thats the two places it will start, so we make the parts out of 304 to make sure you never have a failure!


Here's some air filter and intake system information done by one of our distributors. This is the reason we ONLY sell Pro Guard 7 products!


Here's what Dan Montegari of Precision Diesel Services says about advanced FLOW engineering's Pro-GUARD 7 filter media:


HIGH FLOW AIR INTAKE SYSTEMS
WHO IS THE BEST & WHY!


We received many letters asking which high flow air intake system to use. We decided to test a number of manufacturers’ systems to determine which system was superior. We tested each system and found systems manufactured by AFE (Advanced Flow Engineering) were the best by far.


Diesel engines use seven times more air than gasoline engines of equivalent size so clean cool air is a must for extended engine life, better fuel economy and additional power. A higher flow of intake air coupled with a high flow exhaust system allows for more power, a better fuel economy, extended engine life and reduced exhaust temperatures. On the other hand ingested dirt through the air intake system becomes Silicon in the engine oil, which is a harsh cutting agent and can damage your engine quickly.


We tested three very popular systems. I will not mention the names of the other systems as a courtesy but I will explain what problems we found with them. We evaluated the systems by a number of criteria, filtration protection, flow, and design, easy of installation and cost. Almost in the beginning of the tests we realized in most instances a new intake system was necessary to achieve our goals. We needed a kit that used mostly outside air and not hot engine compartment air. We decided to use systems designed to use mostly outside air.


Two manufacturers claimed their systems delivered cleaner air at a higher flow but this was far from the truth. We did not believe any of the manufacturers’ claims and tested each system by operating the vehicle 3,000 miles and performing an engine oil analysis to determine Silicon levels in the engine oil. The vehicle we used has an engine oil analysis performed at every oil change so we had a Silicon number of three (3) to base our tests on.


The first manufacturer’s system was fairly easy to install but we had problems with the oil used to coat the filter also coated the Mass Air Flow Sensor causing a service engine lamp to come on. I called the manufacturer but they had no explanation as to why this should happen but they had this complaint before. Through the three thousand mile test I had to clean the sensor three times to stop the service engine lamp from coming on. When the oil analysis results came back, it was discouraging with Silicon levels at eleven (11). I almost could not believe the result so we changed the oil and filter and repeated the test. The results were almost the same eliminating this manufacturer quickly. I c
