whens the last time its been serviced? maybe need new plugs. also strut braces can never be a bad thing, sure why not.

What benefit do you see in that?

No back box = no back pressure, which on an N/A means less torque and power!

its an e36!sure it wud be more free flowing get the gasses out quicker

backpressure gets the gasses out quicker, it works under the principles of a vacuum pulling the gasses through iirc

according to wikipedia (can't be garunteed to be 100% accurate) it's 189bhp

Getting the gasses out quicker can be of benifit to turbo cars as it allows the turbo to spool up quicker, but they still need back pressure.

If you want an exhaust and induction kit tha will actually be of benefit then get ones made by reputable companies and designed for your car.
