Is it a bad idea to remove center resonator-with straight 2

For a number of years I ran a straight center pipe first with a stock muffler then with an Ansa ('till it rusted out). Somewhat (but not overpoweringly) noiser than stock, no better (or worse) perceived performance. Got tired of the Ansa on trips, went back to stock system. Much quieter.

Take your pick

system than the BMW engineers???

Stock / Tii / Turbo (if you want to get expensive) exhaust systems flow very well. What problem are you trying to solve?

Cheers!

but I do like the way you worded that about the engineers...very true. I was thinking for flow reasons but also keeping back pressure in mind. I think I made up my mind- Im keeping it and sand blasting it- thanks for the head check

is the resonator there to modulate sound, or to tune exhaust pulses for power output (or both)? There is a lot of anecdotal information about the stock exhaust system and its efficacy, but I have never seen a scientific analysis (e.g., a reasonably well controlled dyno test, showing stock systems vs. headers vs. "free flow" exhaust, etc.) Does anyone have any proven data?

....don't feel bad about questioning whether or not there is a way to improve on the "vaunted" thirty plus year old design of 2002s. Yeah, those engineers were smart but they also had to design a car for the masses thirty years ago, whereas we as 02 enthusiasts in the 2000s often do not fit the 1970s BMW owner profile. Hence the availability of big cams, sway bars, etc. Not to mention the technological improvements made in certain areas over the last three decades. Electronic ignition anyone? Five speeds? Don't even get me started on government mandated hardware that added weight and removed performance or asthetic appeal-bumper overrides, spacers in front to make 02s boattailed, BIG BUMPERS.(resonators?)

Push the envelope and make mistakes. Learn from them and make a better design. Craft your car the way YOU want it to be, but all the while picking up useful information and tips from great sources such as this board.

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
