many People seems to Wonder what the best exhaust is for 325i/330i, so here is how i did it.

my car is a 330i 2006 european edition without secondary cats and extractor headers

This Cost me around 400$ (360 Euro)

i replaced the original resonator with two vibrant 1792 resonators and Y welded to single 2.5 (65mm) pipe and connected the Simons 2.5 muffler.
The muffler is a straight though style muffler and The lenght is 50cm. and a 2.5 dual tip at the end. video of the exhaust can be fixed.

clean setup - very nicely done.

would you recommend the two vibrant resonators to replace the factory resonator?

here is my setup: factory res intact. magnaflow muffler. stock manifold intact. no secondary cats.

thanks

if you have something like AA headers without catalytic converter, two vibrant resonators shoud be the perfect setup.

since i still have OEM headers with catalytic converters, two vibrant is overkill imo.

Go for one if you have OEM headers, and two if you have aftermarket headers.

first i deleted the factory resonator, and then i noticed a drop i low end torque and drone between 2-3k rpm.

after a few months i build This setup and low end torque became Much better! and no drone or rasp either!

Nice noise! Is your engine an N52 or N53?

Nice work, sounds good at idle. How would you compare sound in the cabin at speed?

What are you doing tune wise? That's a very nice sounding n52 mate.
