Hi Guys,

Wondering if anyone could offer some advice. I purchased an X Pipe from CKS for the 171 55. I arranged to get it fitted at a local exhaust specialists. They fitted it, took about 2 hours labour.

I collected and drove home then noticed one side of the exhausts is not aligned / too close to bumper. I contacted the exhaust shop, bought it back and they told me its the X Pipe part which had made it out of alignment forcing the ends. They've said there is nothing they can do. Now its started to rub on the trim. Its so frustrating, I have contacted CKS they have not been very helpful either. They have said they never had any issues and when I asked if I could bring it for them to inspect - they don't have anyone that can have a look either. Conversing over emails and have sent pictures over.

Anything you guys recommend? I m getting so frustrated I want to remove whole thing...
I've been wanting to get secondary cats next, wondering if this would help I don't know.. Been a bloody headache..

I have the same issue but I caused it by putting cf diffuser on.

But I am not concerned as it is close but not touching

i would be more concerned about that huge gap between your bumper and the top of your exhaust

That diffuser looks amazing!

have sent some pics to cks hope they’ll get back to me. Wouldn’t thought there surely must be some adjustments etc..

Been looking at the CKS X pipe and it looks a lot like a Magnaflow with appropriate pipes welded to make it custom fit so maybe it's a build fault. I have ordered a Supersprint which you need sleeve adapters to join at the rear. Their X pipe is good value but the sleeves are £200... I don't think so! They're on eBay for about £17. Stay tuned!

100% worth doing, the noise is awesome :cool:

As long as you have someone that can take a bit of time on the fit, it'll be fine - the guy that did mine knows I'm 'fussy' so made sure it was perfect!

Yep, can hardly wait. Fed up with hearing 4 litre SUVs driving by sounding like Nascar. We have a fab 5.5 full fat V8 and the sound needs to be uncaged!

Had a word with my local Indie. He's good and reliable and confident he can set it up ok but I'll take the X pipe over to him to look over before he takes it on.

No more will you envy the 4.0 SUVs, you’ll put them back in their boxes!!

Great approach, 99% preparation, 1% to perfection👍

Post some pics of the finished job, and a vid of the sound!! 💨💨💨

ROTFL! That gleeful giggle!! Exactly how I feel every time I kick down, even on my bog-standard one! :)

But yeah, I'm going to have to do a header and X-pipe mod next winter, that's for sure!! :D :D :D

If you take your car to an exhaust specialist I am sure they will be able to sort the alignment issue out.
it will cost to get it done but worth it in the end.
I don’t think you will have any luck with the x pipe supplier as it was not installed by them so difficult to say whether it was the part or the install.

Bold move! Think about e-cutouts before the rear boxes. Then the sound can be variably adjusted between no bypass to full bypass of the rear boxes

Link e-cutouts project
Yes, I saw your video on this. Economically it seems like a much better step than sports mufflers and of course you have the choice of stealth or monster sound! I'm intrigued how on the later R172 cars they manage to contain the exhaust gases within the muffler boxes when the flaps are open? In other words, it always comes out of the tail pipes.

Normally the flaps route it trough a bypass pipe in the rear mufflers. Not sure how it is done in a R172 but E.G. The AMG GT uses 1 rear outlet pipe per side for the bypass with the flaps are open. Of course better then dumping hot gasses under the car but I have done this in 3 cars now and never had issues with. Also Dutch ‘MOT’ don’t object as long as the flaps can completely close.

Because of the auto volume level correction of my camera the difference in sound level is not really clear in that video. Actually the car becomes 2 to 3 times as loud on full throttle with the valves open. Way to loud for daily use. Also there then is a drone around 2800rpm. Hence my comment that it is a bold move to remove the rear boxes.
