Title: Best bang for the buck exhaust system?
Post by: dunny on December 25, 2010, 12:58:25 PM

I just picked up a 1991 318i with the M42 in it....and the exhaust is in sad shape.  I'm looking to replace everything from the header back.  While I don't have to have the best, I would like to see a slight performance increase without spending too much money.  I've seen a few setups on ebay for around $350 or so....but everything else I look at is pricey.  What is the best system to go with for the least amount of money?  If all else fails I can have my friend fab one up, but it would be easiest to just buy and install.  Thanks in advance!

Here is the one on ebay I found:

Cheapest is find a stock replacement at a junkyard or something, or if your friend can weld, that would be cheap also.  I have never heard of the ebay one you posted though.

Ditch the cat, replace with a long resonator and a good flowing muffler. Keep the headers the flow really well.

By far the Magnaflow 14815 series muffler is the best sounding as well as price
