this is for my 1999 dodge dakota. im also getting a KN cold air intake and flowtech headers to go with the new exhaust so which would be better, the system or just the muffler?
Because you're getting headers and a cold air intake, your truck will benefit more from a full cat-back exhaust. Most performance cat-backs are larger diameter than stock and many are mandrel-bent as well, which means much better flow. If you just replace the muffler you'll still have the restrictive stock exhaust on either end of it. You'll save money over a cat-back but you'll have less horsepower too. An engine is basically an air pump, and the more efficiently it can get air/fuel in and exhaust out, the more power it will make.
You don't need a tune. unplug the battery for 30 minutes and the computer in your car will reset its self. The check engine light is prolly on because you didn't add O2 extensions after adding your O/R x-pipe. Go to your local auto parts store and they can read your check engine light for free. Im a fan of Auto Zone my self. Good Luck.
The KN is great, FlowMaster is good, too. Ask the Flowmaster exhaust experts your questions. Specifically about you r vehicle. Remember, noise does not mean power.
i obtained a 89 supra rapid had the historical inventory exhaust ripped off and threw on four inch catback hello float exahustshould you simply desire the sound long past do just the mufffler, you more commonly obtained a well satisfactory exhaust so dont take all of it off.
The air intake is hot becaust the under hod temp is hot. heat is radiated to all under hood components. That is y a good cold air kit takes air from in front of the radiator.Where the air is still cold.
