I tried searching the forum for posts on this but couldnt find anything. This mod looks neat and easy. Has anyone tried it? Does it look like it would fit my 428i with the M Performance exhaust on my N20? It looks great, but I am not going to mess my exhaust up for no reason.

Thanks for your thoughts!

Following this. I don’t know how I feel about this just yet... but anything can fit if you try hard enough lol

Well thats interesting. I guess you just cut or pull the tips off your 328i muffler and slide this on and bam, QUAD EXHAUST lol? Not sure if thats the idea or if it even fits, but okay lol its different.

You'd have to modify the rear bumper shell, too. I think somebody sells a template for adding the M Style exhaust to non-M cars.

On the other hand, you could keep the stock 428i exhaust and spend the money on actual mods... so you would have a sleeper that could embarrass people who don't know what to expect. It's always cooler to have a really fast car than an M wannabe.

I agree, My car already has a JB4, downpipe, charge pipe, intercooler and other mods. I am close to running out on anything that can make cheap power!

Keep in mind that you get diminishing returns as you mod. With that work, you will get a smaller HP increase from an exhaust than you would get on a stock car with nothing else.

look like something a local muffler shop can do. Seriously why give your business else where around the world. The photo in the link provided just look so cheap.

seems like it would be better to just have a exhaust shop weld on a y pipe and route it out to quad tips, rather then having 1 fake tip and 3 working ones...
