Has anyone here ever experimented with dual exhaust on the A4/S4? And I'm not talking about just gettin exhaust tips with two pipes commin out the same side. I talkin about something like this:



I love the way it looks, I just need to know if it feasible. Anyone?

 

Read this post...

 

Hmmm... that was helpful enough to let me know it's not going to be very easy to get dual exhaust, but I'm wondering if it would be any easier with a 2.7t (ie. the S4)? At this point I think I will put it on the backburner, but I'm definitely going to pursue the option.[sm=smiley15.gif]

 

I think the main factor is the location of the fuel tank and other parts. There really just isnt room. I've seen setups where the muffler has another pipe running out the side that goes to the right side tips. Thats not really a "dual exhaust" though. Search Audiworld.com for a little more help.

 

Ditto what jestnomen said. The underbelly anatomy doesn't allow for the splitting of the S4's dual to exit on both sides.

BTW: I looked into that set-up in the picture you posted a year ago - the effect is purely cosmetic. It isn't a true split dual down the underside of the car. It is in fact a splitter at the rear that routes the additional pipes to the opposite side.

 

Weak sauce man.... weak sauce....

 

Yeah.... looks cool though!

 

Yeah. I can't get it out of my head even if it is essentially non-functional. I may still want to do it, it's just gonna be a hard decision cuz I dont really like putting stuff on there that doesn't have a necessary purpose. I think I would place it in the quasi-functional catagory being that it does work, but not necessary as to the increased flow of exhaust.

 

With some cutting you MIGHT be able to make it work, havent studied the undercarrige that much, but it would be awesome if you could make it work, like a real dual exhaust.

 

I think it would be a really tight fit to do a true dual exhaust system and probably not worth it, but if I were to do it, I would split the pipe near the rear and divert a section to the other side. Granted I won't be doing any exhaust work until I upgrade the turbo, I will have plenty of time to work out a design that will work. Not to mention when I upgrade the exhaust it won't even really be necessary to have dual, so it'll most likely be functional but pose no advantage, thus making more for show than anything else.

But I guess we'll see what happens....
