I bought a sport quiet muffler and it has 4 inlets but my heat exchangers have 2 outlets with a different bolt pattern. Are my heat exchangers non-standard or did I buy the wrong muffler?

Yikes! that is xee! glad i bought some 30 years ago when relatively they seemed affordable. even in 94 i found ads in old mags at $190 a side. that would be about $400 a side in todays money if straight inflation. maybe you can rustle up a second hand set. they are durable so it should be possible to find some in good condition. i could be wrong but i think its very difficult to buy any kind of final muffler set up for the cat cars of 75 on. all i have seen are the standard vw mufflers (repro like dansk or old stock if you are lucky) or the muffler you have. all have twin outlets. my problem was a headache here in aus as you can't get a 914 specific muffler at all, got to ship in at great cost. but you can adapt a kombi muffler. but again thats got twin outlets. |
