X-pipe options? Help!

So I am undecided on what x pipe to run for many reasons. My dealer will not allow me to replace the primaries without voiding my warranty (so dumb) but whatever. That leaves out high hp pipe setups like gintani/rpi/ipe out

I currently have the meistershaft gt2 and when an x pipe is combined with that rear section, things can get ugly lol

Would you run the meistershaft lx pipe or the challenge street pipe? Both do not replace the front pipes. By keeping primaries, will that allow for no check engine light?

Thanks in advance!

Retaining primary cats and 4 sensors in their current locations = No SES light.

Im leaning toward the meistershaft lx x pipe. Does anyone have this pipe and can confirm no check engine light?

There is little point in removing the secondaries. Very meager power gains overall and lots of drone unless the cats are replaced with resonators.

I just want a little more power, little more sound, and keep the warranty.

So you'd reccomend a x pipe with hfc's and resonators?

Why would you tell your dealer??

Just go catless and keep your stock x-pipe just in case you need to switch back.

word of advise. don't touch any cats if you care about warranty. cats deleted are not viewed very good in dealership or BMW eyes. you change the air flow and commit a federal crime. ( i know no one gets caught). but still there are shops that don't even touch cars with no cats. for that reason.

the real gains are within the primary cats. you want more sound and wanna be warranty safe? delete your resonators. that with a GT2 i promise you this. you will LOVE it. i had incredible results with my recent delete. car went from to quiet to beast mode. not even kidding. your going to laugh when you see how much louder your car gets.

1st sentence. There are before and after O2 sensors. Secondary cats are not monitored.

I had the Meisterschaft gt2 exhaust with sr connecting pipes installed a few weeks ago. Exhaust sounds aight but honestly not too much louder than the ACM exhaust mod imo. I am having the Dinan x pipe with the 4 resonators installed tomorrow. Hopefully it will produce the sound I am looking for. My ses light did come on but maybe it was because I added the sr pipes.

The lx x pipe or you're referring to the sr pipes?

If you went fully catless with a Meisterchaft GT2 you will go deaf, main reason I got rid of mine. But if you must, I would look for a high flow with resenator option like challenge, Gintani also offers a HFC option too.

Haha! I have challenge race sitting in my garage and I refuse to put it on lol

Im concerned with noise but not too much as i barely drive the car. I just dont want the bmw dealer to be like oh, you're catless thats why your motor blew. bmw is the worst. They tried telling me that my tpms malfunction was from installing coilovers lol! Im like no....

Im trying to stay away from this again. I've built crazy cars but no sense in voiding a $80k car warranty over replacing cats. Ill put an ess 625 kit on at that point.

If you are concerned with warranty, just go with Dinan then. They are expensive, but they can match BMW warranty. But then you'll need tune.

IMO, if you are going to mess around with x-pipe, the primaries have to go.

I've got the GT2 (titanium) with SS SR pipes and I think it's crazy loud and sounds intoxicating. Not sure how going catless or resonatorless would sound to be honest, but I would imagine deafening. Whatever you end up going with please post videos of the results.

The dealership cannot void your warranty for you removing/replacing parts on your own vehicle.

BMW NA can deny any claim you submit and say it is because of the aftermarket part, but they cannot void your warranty preemptively. Additionally, the burden of proof is on BMW NA to show evidence the aftermarket part caused the events leading up to the claim.

No. An 'aftermarket' part is a part made by a company other than the vehicle manufacturer or the original equipment manufacturer. A 'recycled' part is a part that was made for and installed in a new vehicle by the manufacturer or the original equipment manufacturer, and later removed from the vehicle and made available for resale or reuse. Simply using an aftermarket or recycled part does not void your warranty. The Magnuson-Moss Warranty Act makes it illegal for companies to void your warranty or deny coverage under the warranty simply because you used an aftermarket or recycled part. Still, if it turns out that the aftermarket or recycled part was itself defective or wasn't installed correctly, and it causes damage to another part that is covered under the warranty, the manufacturer or dealer has the right to deny coverage for that part and charge you for any repairs. The FTC says the manufacturer or dealer must show that the aftermarket or recycled part caused the need for repairs before denying warranty coverage.

If you have to/want to keep the primaries, just get a good axle-back and call it a day. M Performance Exhaust on stock x-pipe is ideal, IMO.

This is perfect! Thank you for the info!

I really want to replace the primaries with HFC's at the very least

Meistershaft lx x pipe is out of the question. It requires cutting to tbe factory front pipes. Id rather do one whole gitani or dinan pipe and remove it if necessary.
