A customer has asked me about making one of my Stage II EVO systems with a center outlet instead of in the stock location. I am pretty sure I can do this nicely with a few key alterations to the muffler layout. It will allow the muffler to be centered in the back instead of offset to the left side.
What do you think? Attached image(s) |

Look at the Ailen photos (IMG:http://www.914world.com/bbs2/html/emoticons/smilie_pokal.gif) I was going to do this also.

Wouldn't it be kinda low to miss the tranny or do you bend the pipe aft of the tranny to exit at the center.?
I like it. (IMG:http://www.914world.com/bbs2/html/emoticons/wink.gif) |

Some mufflers have a center exit with a pipe extending the tailpipe to the side.
I like the idea. The PO of my car did something similar by editing the tail pipe after the muffler. Its not quite perfectly centered, but pretty darn close. I'm sure anything Chris puts together will be leagues better than this, but here's the best image I have handy that shows mine. Not quite as nice looking as a Boxster...haha...maybe someday.

Do a twin pipes similar to the Boxster S, that would look sweet....

This is what I did. I'm re-doing my system completely this year. It's too restrictive. I'm still going for the center exhaust, (same mufflers facing each other) but I will get mufflers with larger inlets, and large duel outlets. I will use one of the outlets as a cross-over or balance pipe and the other as a combo center outlet. (larger, of course) I plan on adding tubes on both sides of the straight exhaust section for a heat exchanger too. I think there's room. I'm also going to use all mandrel bent curved sections

So far all the comments are positive. To me, those center exhausts look too much like a sphincter. But hey, to each his own..... |

Thanks for all the comments.
I was thinking a Boxster oval would be nice, and I thought about twin tips like a Cayman S too. I don't have much room to work with so it will probably be a 2 1/2" polished stainless round tip cut on a slant. |

I've always liked the center tips idea. The older 356 Carreras and 550s had them--called Peashooters.
The 935s used them, as did I on the black biturbo. The F40 Ferrari had em too, and now the 986 and Cayman. Mig welder and mandrel bender= No limits (IMG:http://www.914world.com/bbs2/html/emoticons/idea.gif) Marty Attached thumbnail(s) |

Sheesh Marty, quit posting pics of that slow POS already, haha.
I noticed you have a 3'rd pipe, like the F40 had, is that for something with the turbos? |

I think that's the way they should have been from the factory... in the spirit of mid-engine Porscheees that came before them.
Rocking idea. |

Nathan, that's exactly what the smaller center tube is for. I bring the excess exhaust out of the wastegate, down around the transaxle, and dump it to atmosphere in between the other 2.
It's pretty slow...for a jet. Marty |

Well, I guess I have to go with twin tips. (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)
I'll post pics in a couple of weeks once I've made some progress. |

Start collecting rear valances to mod and sell as a package welder-man.

That same "customer" is the guy that has 202 RAT ponies to unleash.....(2316cc) His Kerry Hunter certainly was not up to the task. Chris, the center outlet has been asked about many times by my customers, people like the look- especially the 356 guys! |

If it has to be in the sphincter section, at least make it a twin!
BYW, Maltese Falcon, what wing is that on your car? PM me if you have any details. DaveC |
