1995 BMW SuperTrapp

Hi guys this is my first post here.
I have a quick question for you guys.I'm thinking about replacing my standard muffler with a SuperTrapp SC. I have had them installed before on my 1969 2002Tii,where I had my fuel injector replaced with a twin side draft WeberDOCE45's, a Sthal Header(short) and a twin SuperTrapps,That thing would howl like a wolf going down the highway while shooting flames out the pipes whenever I down/up shifted hard............of course that was my money pit too(LOL)......when I got married ,the 02 was the first thing to go,after that I went through a 1994 740il then 1997 M3 ,until I finally settled in a 1995 525i(a fall from grace,LOL). anyway,I have been working on fixing /upgrading things on the car.One of those upgrades that I would like to undertake is installing a SuperTrapp on my 525i............has anyone done that or knows of someone that did it?...please let me know,and try to be kind and not rag on me for my recent car choice.Thanks

Yes, 02 pics....

No reason that you couldn't fit a Supertrapp to the 525. You should be able to taylor the sound to some extent with the baffles. I do not recall anyone else having tried it so go for it! The six will sound much sweeter than the four... you wont shoot flames out the back unless maybe... you straight pipe it back to the muffler and richen up the mixture a bit

I removed the muffler from my 535. Howls pretty good under the whip, obnoxious for daily driving

Good Luck

OUCH !!!!......................man ,talk about a beat down,lol. I will upload the 02 pics,got to go through my old hard drives to pull it out.
BUT,back to reason for asking,is because on the 02 I had a single 2 3/4 run from the headers to the back and ,in the beginning i only had one SuperTrapp,I later acquired a second one and had the muffler shop make a Y connection so I can run both. I think the 525 runs 2 pipes to the back,so I guess I would have to either modify the pipes or put in a Y connection to make it work.

P.S. I would run that thing without the baffles ..............ran my 02 for 10 years that way
