73 tii exhaust & unrelated valuation question


Recommended Posts

So, two totally (mostly) unrelated questions here:


First, the easy one:  73 tii with stock tii exhaust manifold.  Muffler and exhaust pipe are finally rusting/rotting out.  Car sounds like a Honda (insert cringing sounds here).  entire exhaust system should be replaced.  My mechanic is suggesting that I keep the stock tii exhaust manifold which will provide better performance than going with an aftermarket header.  He is suggesting just replacing the pipes from the manifold back with a new stock-ish muffler.  I want to put something on the car that helps performance and gives it a nice sport car rumble, without making folks think I'm trying to be 19 again.  What do you think?  And, for those who have gone with a performance muffler set up, what have you used.  I had a 75 02 with an Ansa muffler that I liked, but I'm wondering if Borla or Magnaflo might be an equally good option but might cost less.  


Second, the harder question:  how much of a value difference do you think there is between a stock 73 tii and 73 tii that has been transplanted into a 70 1600 body?  20%? 30% 50% value difference???  Assume the following to be true:  both cars are drivers.  Both are equipped the exact same way (5-speed, rebuilt motor, rims & tires, suspension, interior, paint).  For the sake of this exercise, assume that both cars really are equal in all respects, except the difference in the body.  This is just an academic question.  


Thanks a bunch!

A 1970 1600-2 with a tii engine (and front struts, and boxed trailing arms, and etc.) is simply a 1970 1600-2 with a tii engine: it neither becomes a tii nor accrues a tii's market value.  Cars are defined by their VIN's and the VIN generally goes with the chassis -- unless you're skirting the law...


There are lots of good threads on here about non-stock exhausts.  Have you done a Google search on the forum with a search string such as "exhaust replace"?

You will ruin both cars. 1600's are getting more desirable too. 

Not suggesting I want to to do this.  There is a care for sale someone has already converted.  I'm thinking of buying it, but I'm trying to figure out  what the real value is.

I would keep the stock exhaust manifold for a non hot rodded engine, the factory did do extensive dyno testing on the m-10 and for the most part got it right, as to which aftermarket exhaust go through the threads here, a few of them have audio clips, and find what your looking for it's up to your taste.

After 30+ years of 2002ing...and countless aftermarket exhausts....I have come to the conclusion that nothing fits or performs as well as the genuine BMW exhaust, on a tii. Yes...it's quiet, but the car runs stronger / better than ever. Ansa rots out or comes apart internally, the IE stuff does both *and* cracks / requires fitment fiddling. Ansa or Bosal (not to be confused with BOYSEN - which truly IS one of the original manufacturers for BMW) "stock style" is less expensive than the real deal BMW stuff, but you may end up replacing it three times, versus the life span of a genuine system. Exhausts aren't cheap, but if you can forego your desire for "sporty sound" and can fit it in the budget, it's the way to go . 


Just my experience... but man o' man do i LOVE having a stock factory BMW exhaust again!!!!

    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
