2002 Dakota 3.9L exhaust

From : doug hutter

Q: i just got an 02 dakota and was thinking about doing a dual exhaust and a/c with k&n filter to help it breath better....maybe a couple more horses ya know so i stopped by the exhaust place that did the pipes on my 36 chevy delivery and asked. heres what i learned because the system has 2 oxygen sensors before and after the cat. converter the best they can do is a 3 dual exhaust with one muffler after the converter. or they could open up the end of the converter stock is 2.5 and add the exhaust from there... but he said that would void the warranty. truck has 15500 miles; warranty is 7 yrs/72000 miles im thinking mostly this makes no sense... the dual pipes would be just for looks... no advantage in taking two pipes from the headers thru the converter and muffler then back to two pipes.... am i right anybody done anything with the exhaust with a later model dakota results how about the air cleaner/air filter any suggestions .

bottom line is if you wanted power you shouldnt have bought a 3.9 v6 to me a split exhaust on a v6 sounds like a hopped up chainsaw anybody done anything with the exhaust with a later model dakota results how about the air cleaner/air filter any suggestions ill start watching reality tv shows when i can vote people off the planet. .

i have checked and as of a couple months ago k &n did not make the intake fipk replacemnt for the late model v6 dakotas. other companies say they have one unit that fits both the 6 and 8 cyl but not a k&n. im still waiting! not sure if using the hypertech tuner is going to help on the v6 the way it did on the v8 mentioned up this thread a few. anyone with experience on the v6 hypertech tuner could leave us a note and it will be appreciated. ciuo i just got an 02 dakota and was thinking about doing a dual exhaust and a/c with k&n filter to help it breath better....maybe a couple more horses ya know so i stopped by the exhaust place that did the pipes on my 36 chevy delivery and asked. heres what i learned because the system has 2 oxygen sensors before and after the cat. converter the best they can do is a 3 dual exhaust with one muffler after the converter. or they could open up the end of the converter stock is 2.5 and add the exhaust from there... but he said that would void the warranty. truck has 15500 miles; warranty is 7 yrs/72000 miles im thinking mostly this makes no sense... the dual pipes would be just for looks... no advantage in taking two pipes from the headers thru the converter and muffler then back to two pipes.... am i right anybody done anything with the exhaust with a later model dakota results how about the air cleaner/air filter any suggestions .

the factory exhaust on that truck is fairly well designed from the factory. the best you could do is a gibson stainless steel catback exhaust specifically designed for the truck. the single side swept really is as good as they get with minimal increase in annoying noise. about $600 installed. best improvement will be about a 1.5% to 2% increase in power. almost nothing worth $600 aluminized steel will only last 2-3 years if you live anywhere they use salt on the road. the factory is a semi-stainless steel exhaust. a properly installed catback ss system will not void any warranty except for the warranty on the exhaust from dodge. if they do a botch job them who knows. david i just got an 02 dakota and was thinking about doing a dual exhaust and a/c with k&n filter to help it breath better....maybe a couple more horses ya know so i stopped by the exhaust place that did the pipes on my 36 chevy delivery and asked. heres what i learned because the system has 2 oxygen sensors before and after the cat. converter the best they can do is a 3 dual exhaust with one muffler after the converter. or they could open up the end of the converter stock is 2.5 and add the exhaust from there... but he said that would void the warranty. truck has 15500 miles; warranty is 7 yrs/72000 miles im thinking mostly this makes no sense... the dual pipes would be just for looks... no advantage in taking two pipes from the headers thru the converter and muffler then back to two pipes.... am i right anybody done anything with the exhaust with a later model dakota results how about the air cleaner/air filter any suggestions .
