Supersprint Downpipe for the 328, 428, and 228. Fits N20, N26 engines. Supersprint is the highest quality downpipe, there's nothing of higher quality. It fits perfectly the first time, reducing your labor costs when installing. It flexes, just like the OEM downpipe, to protect your engine from damage. Only 8k miles on the downpipe.

Performance gains on a heavy F31 328xi Wagon with N26 engine:

This is the same downpipe that Supersprint sells for the 428xi, part 987311. So yes, it will fit on your 4 series! Last time I went to the dealer, I went for oil and new brake pads with the downpipe on and everything and they did it all for free like normal, they didn't care.

I think when it comes to after market mods, the dealer doesn't care unless it could be the reason why something broke. Thats why you want to go with Supersprint vs something like AFe which doesn't have the flex part. My shop that did the install said people come in all the time with cheap downpipes that take them HOURS to install because they have to do modifications to make it fit. Whereas Supersprint always fits perfect. They are rare though because they have to be imported from Italy.

Good to hear that！ I am planing to get a quad exhaust with center pipe form supersprint soon. And if I wanna use the down pipe I have to go with JB4 right ? In order to cancel to error code?

Yeah, you wont see much performance boost without the JB4. When you have the downpipe installed, you can set the JB4 to Map 2 (don't use map 2 if you don't have a downpipe). As you can see in my post, Map 2 with the Supersprint downpipe made me 1 second faster to 60mph and put my 328 Wagon toe-to-toe with M3s!
