This project(like all the others) has been on the "to do "list for awhile.
The mufller fits in the stock location pretty well even with the heat shield in place. If the heat shield was removed, it can go a little higher towards the trunk. I decided to go all stainless , which aint cheap, but will pay off in the long run. After all the hard work, I fired it up last night and I have an exhaust leak at the heads. It was 11pm so I shut the garage door and went to bed. I'm going to chase it down today. Here are soem pics. The first two show the hagers that need to be cut off. there are two on top that are threaded studs and to hangers on the back. Attached image(s) |

From what I have researched when I was looking at purchasing a Boxster several years ago the mufflers are pretty efficent in that most aftermarkets do no make significantly more power. I have a Boxster S muffler sitting in the corner of my garage awaiting testing. Should be said I only have -6 (914 and 911) to work with. I dyno almost every modification I do to verify if its worth doing.
That said for a small 6 a early 911 muffler (2 in) converted to sport with to two center outlets is within a couple HP of megaphones. Only downside is that is quite loud. I am expecting that a Boxster S muffler made for a 2.5 six with 250HP will make similar HP and be much quieter then sport muffler I am running now. When I get around to testing I will post the results. -Some other recent dyno testing I have done on small -6 engines. https://forums.pelicanparts.com/porsche-911...-2-4l-2-5l.html I bet that these muffler made to work on newer cars with 200-250 will work good on 914's making 100HP. They might be 10lbs heavier but that is nothing compared to the lightening most Driver could do to themselves (i am in this camp) (IMG:style_emoticons/default/biggrin.gif) john |
