Looking for a little help.
I’ve a ‘75 (originally a 1.8) upgraded with a ‘73 2.0. I need a muffler, but am a bit confused on which one. The heat exchanger exits into a single throat, triangle flange. I ordered a used Bursch for a ‘73 2.0, but it’s a dual-throat ‘in’ and the trapezoid flange. Reading other threads/classifieds, the one I received should be the correct one. So, different heat exchangers for different years of the 2.0? I’m running a 4-tip Monza that’s rusted out. -TK |

Thank you all for the clarification. Now I know, and will be selling a muffler soon.
Cheers! |

Cheers! just my opinion but unless you have a very original OEM concours car, i recommend getting the better more open HE, get the 2.0 to match your muffler. those 75 he were the worst most restrictive set up and cost you some significant HP> either way enjoy, but get some new HE those old ones probably leak anyway- you can test to make sure , dont assume. |

This is a good point. Since your exchangers are older and you have the muffler off, get a borescope off Amazon and inspect them. Rust/burn out can't be seen under the air jacket from the outside. But holes in the header tube will pump carbon monoxide into the cabin if you have heat hooked up. Even better is to smoke test or pressure test, but if the exchangers are attached to the car a borescope will likely tell you what you need to know. Zach |
