loudest exhaust
 

What is the loudest combination of headers/exhaust for a 2001 e53 x5? i was thinking Kelleners exhaust system.

just run straight pipes with no mufflers.

Or remove the headers :o

Interesting and informative answers. Go with an Eisenmann race with no resonator! It will be loud! I am not familiar with the Kelleners system. Do you have a link to their system? I have a Supersprint and it has a nice rumble but not quite loud enough!!!

Here is the Eisenmann link:

That would result in bent valves from the change in heat...:rofl:

Still..loudest exhaust would be no mufflers...not that it would sound good.

Try to snag those for a good price

Dinan does have a great sound to it!

Open header.

I do like the eisenmann's alot, especially since on the scale of loudness 1-10, the race exhaust is an 8.8 :) and the sport is a 4.4, and only for 1.7grand. BTW silver, the link to eisenhaus u posted, they also sell kelleners lol, it says it right on the main page. Anyway, i think i'll go with the eisenmann's race exhaust, but can anyone post some links to any great sounding loud-ass brands of headers? My buddy is comin over with his ford lightning tomorrow, hes got the loudest possible combination of headers, exhaust, and muffler out there for his lightning, so i'll see what he can tell me. Keep posting people, i'm really in need of help (in no urgency though)

I really think the headers are overkill. They are quite expensive, if you can find them, and in terms of "bang for the buck" I don't think you get your money's worth considering the cost of the headers and then installation. If it is a diy it would be a big project to install them! Save the $$$ and buy an exhaust and a chip!!

Get the Eisenmann and if it is not loud enough remove the resonator with an X-pipe.

What engine do you have??
