Re: E30 Exhaust Questions - Catalytic and Muffler (archive)

After 160,000 miles, I believe it is time to replace my 1990 325i exhaust components. My exhaust makes a healthy groan now and I would rather have a quite setup. I was wondering if I could just go to Midas and have them put in a universal cat and muffler setup. I know it will be a lot cheaper than the stock stuff, but I also wanted to know if it will affect the engine performance in any way and will in affect fuel economy.
Any Info will be greatly appreciated!!

'90 325i

The convertor shouldn't need replacing unless it's come apart inside, is rusted, or clogged up. I just bought a new ANSA cat-back muffler for $75 because it had a slightly bent tip easily straightened with a pair of pliers. Midas will charge you more than that to cobble up something that'll work. In fact, that's what I just took off my newly acquired 90 325i. A cobbled up Midas muffler mounted backwards, single outlet in (Y'd the original exhaust pipes into it) & single outlet out. Of course I had to buy new muffler brackets since Midas cut and welded them. Go with a system designed for the car if you want it to run right and sound right. Ansa's are under $200 new for the cat back system I believe and all you have to do is bolt it on.
