Just got this e-mail, how true do you suppose the numbers are. I was surprised that they didn't go to a 5&quot; being the stock system is 4&quot; after the muff already.<br><br><br>Dear 2003 Dodge Owner:<br><br>Just a quick note to say that we have released the 4&quot; Stainless Steel<br>Monster Exhaust for the new 24 Valve Diesel. The demand for this exhaust kit<br>is high, so feel free to call and ask any questions you may have. The<br>Horsepower gain is 18HP and the Torque gain is 30LBS rear wheel torque with<br>the exhaust alone. <br><br>Best Regards,<br><br>Patrick<br><br>Gale Bank's Engineering<br>546 Duggan Avenue<br>Azusa, California 91702<br>800-438-7693 Extension 4127<br>www.bankspower.com<br>

 

I don't know how true that is. I find 18hp/30tq hard to believe. Maybe 1hp/3tq. Why don't you buy it and test it for us?

 

That is why I ask, I find it hard to believe also. Figured some one else would test it for me, don't know how much faith I put in Banks stuff. :

 

For what it's worth, there is another company that is advertising a 4&quot; turbo to tail pipe, and they claim average of 19hp/43tq at the wheels just from changing. I don't know if I believe all of that, but I'm sure that the upgrade to 4&quot; all the way through has to help with EGT.

 

The exhaust has got to give some power, not that much though. All I know is when I was dead stock (even exhaust), I raced my friends 01 Crew Cab Shortebd 4x4 PSD and he beat me. After the exhaust, I beat him. So it does add some power. I don't know about 19/43 though.

 

A H.P. gain of 18 and 30 on the torque????? :<br>I don't think so!!<br><br>I would like to see that on a dyno other than theirs!<br>ALOT of testing has been done on these diesel exhaust<br>systems (4&quot; and 5&quot and the numbers posted by Banks<br>seem high to me. I can tell you this, when I installed<br>my 4&quot; exhaust I saw NO INCREASE in H.P. or torque<br>and that was on a Mustang Inertia Load Dyno. But,<br>that was on my &quot;old&quot; 96' 12 valve. Maybe the new<br>03' common rail engines respond better.<br><br>---------<br>John_P

 

Uh Oh, now Banks has your email address, they will probly start spaming you trying to find out when you will buy a full kit from them...<br><br>They called my every other day for 2 weeks when I emailed them and said I was interested in their products....of course that was when I was young and dumb and hadn't heard of the DTR.

 

Yea they left a answer on my machine at home also, <br><br>To bad for them I think I am going to go with the Edge Comp with the new in cab controls..
