Borla completely re-engineers the exhaust on the E46 325/330 with a tuned all-stainless cat-back system. The E46 Borla bolts straight to the factory manifold and uses all of the factory hangers for an easy and seamless install. Your factory exhaust can come off as one complete piece and bolt this in its place! This is a full stainless system - T304 inside and out for maximum corrosion resistance. The Borla flows better than the stock system too for increased performance, even over the stock ZHP system. But we love the sound of this system the most - deep and with plenty of rumble to set it apart from the stock sound. It's a tuned system, with front resonator and rear muffler, to be louder than stock but not excessive. It's also a lot lighter than the stock system at only 33lbs from nose to tailpipe.

Read what Borla owners have to say:
"The difference over stock is noticeable the instant you turn the key. It begins with a deep muted rumble at engine start. Between 1200-2000rpm, you are treated to a nice throaty (and somewhat loud) growl. Between 2500-3500rpm, the deep growl reveals a slightly deeper, more melodic mechanical rev-up. Once past 4500rpm, the car begins to sound surprisingly stock, all the way up to redline. Lifting off the gas reveals a slightly more pronounced "burble" that settles into a low rumble as revs drop back to idle. At steady cruising speeds, the exhaust does not drone. Planting your right foot brings back that wonderful low growl."
"...the Borla is a very well built unit. Very civilized exhaust note... more agressive, yet not obnoxiously loud."
"I can easily say the Borla exhaust is much better than the X&X exhaust. My brother has the Borla on his 330i ZHP, and I had the X&X on my 330i. The X&X exhaust didn't have the quality of engineering compared to the Borla. The X&X was louder, and had horrible resonation - unacceptable for street use. The Borla is bolt-on, excellent quality, and hangs perfectly straight. The sound is a bit louder than stock, yet never "rice" or obnoxious."

Every Borla is made with 304 stainless steel for the internals and muffler body. Unlike other systems that can use coated aluminum, mild steel, or 409 stainless, the Borla uses true 304 stainless on the inside as well as the outside. This prevents the muffler from rusting and deteriorating from the inside out. Borla guarantees every muffler with a 1,000,000 mile warranty. Turner Motorsport has been the leading Borla dealer for BMW exhausts since we sold our first system in 1996, including using Borla Exhausts on all of every Turner BMW racecar.
