Looking for some input on a new exhaust system for my e32 750. Has anyone seen or heard the tri-flo muffler?
Guysimpson are you happy with your set-up? Did you install headers?
Thanks for any input.

Wow.. thats a fast 7.. Ive never really heard of many people modifying their 7 series BMW. Pretty :cool: of ya..

holy $hit, 160 shot NOS!!

Well, considering the 5.0 V12 is like 2 2.5 I6 motors put together I guess 2 80 shot kits of NOS isn't bad. That is one fast 750il.

Hello Brian, long time no see :D

Here are your options

1. Supersprint. Alot of people really like their stuff. Cat back all SS. And easy to source.

2. Dinan. Too expensive. Steve just takes a stock BMW part and removes enough guts to make it where he likes it and charges you a bundle, but he does live his motto. "We do go not show"

3. Racing Dynamics. :mad: They are really pissing me off these days. No more headers, supposed to be able to get new all SS cat back systems and I don't think any more older systems (aluminized steel) are available. Federico just doesn't seem to be making the 7 a priority these days.

4. MK motorsport. :D Really starting to warm up to this group. Headers, and catback available in all SS through Dazz Motorsports. Pricey but good stuff.

I really like my RD system. So far just cat back. Older style for a 750i Euro. I bought the SS headers and the catless piping but as it's for a i and not a iL I'll have to add about 4" to them. Sound is great at idle and above 2800RPM. Between there sounds stock.
Spool up time is reduced a little too.

Headers not installed yet. Still procrastinating because the header install is so difficult on the driver side. Alot of shit will have to be removed to install them.
