Manifold

Hi all Any thoughts on a tuned round exhaust manifold, coupled to the two brothers system ( with K& N ) filter , must give more power ? Just another thought regards nico 75

It doesn't really matter what you do to the manifold, air intake, exhaust, mufflers, cat converters, or anything else you can swap by unbolting/replacing; unless you get an ECU Upgrade or something like a PowerCommander or a piggy-back chip, you really aren't going to get much improvement in overall power at all!! :lecturef_smilie: At best, you might get something hardly measurable, at worst you'll kill some sector of your rev range &/or hammer your fuel economy!! :shocked:

So unless you're planning an ECU Upgrade or similar, you're really only playing around the edges & fiddling with noise & appearances, & probably doing more harm than good to boot!! :gaah:

" NO " …..read post #2 ... :roflblack::roflblack::roflblack:...… Mike :ohyea:

The computer and its sensors do a great job of taking any changes it senses and changing the timing, mixture, and other parameters to bring performance back to its’s programmer range. So pipes and mufflers will only change the sound. Only an ECU flash will actually change performance.

Ok Peter good advice noted regards nico 75

Ok all noted ref manifold regards nico 75
