For the Belanger/Headers guys

[oxam]

I love the sound of the Belangers (no real power gain compared to the stock 2002 headers btw) but ever since I installed them I am getting a weird vibration/resonance between 1.700 and 2.000 rpm. I read on the alley that could be also attributed to new engine mounts and poly gearbox mount. The exhaust is Belangers into 3" 200 cell Metallic cats into 3" borla sill mufflers into 3" straight pipes.

any ideas guys?

Side exits I guess - are the sides balanced to each other (connected) - not sure how this is done (if atall) for side exits but my rear exit has a balance connection and I don't suffer vibs or resonance anywhere and also have new/stiff engine mounts.

I have rear exits as well...will look into making an H pipe then. Not sure about the impact being so far back though

I've got Belangers into race-cats (sorry dunno what make - bought'em used), into a Corsa cat back. Only vibes I get are good ones

Finally got around to loading a picture.
