If you loosen all 4 clamps, you can rotate the link pipes and get to a position that you like and tighten. As much as this system isn’t very easy to get perfect, I do like there is a ton of adjustability for aligning.

Nice install! That’s how my pipes sit also. Some realigning should be good to go.

any update on getting some heat in the exhaust for gapping the exhaust tips even? If this gets resolved by simple heat/driving, im going to order one!

Only thing I’m not thrilled about is that the valve springs might need some tweaking. In comfort (valves closed), the left valve does not close 100%, so there’s some bypassing fluttering noises. Amplified during cold start. Otherwise, exhaust in sport+ sounds absolutely epic. No drives yet, but even with just revving, it’s a great sound.

Also noticed the left valve not closing all the way in mine, too. Minor fluttering noises but nothing to bother me. Let me know what you do to fix it.

The gap is definitely a little smaller on the left side, but it really doesn’t stand out much.

The trick is slightly bending the steel spring that sits between the controller and valve slot. I was able to tweak mine in a vice so the left valve is fully closed now while in comfort. Slight fluttering sounds there (bypassing, OEM exhaust does this slightly as well) but nothing like it was with the big gap before.

First drive this morning, nice deep sound, and this setup looks incredible from the rear! I was expecting it to be a bit louder under load (seemed very loud free reviving), but I think my resonated single midpipe is keeping this quieter, which is ok with me.

My only complaint; I’ve spent a few hours fine tuning the left valve assembly. There’s a very small threshold to get it just right (by tweaking the spring that sits between the valve and controller). Too loose, and you’ll have some bypassing noises. Too tight, and the valve could vibrate against the gate in the pipe. Not a very big deal, and I’ll probably continue to tweak the spring.

Overall, very happy with this exhaust. I’ve mentioned it before, but due to the two sections, and adjustable tips, this system has a lot of adjustability. May be annoying to some, but I love that you can truly fine tune this thing to sit how you want.

[Ariboon]

just placed an order on the midpipe and exhaust. will update once installed!

[FISH22]

For anyone interested in trying this exhaust with valves fully open; it’s not as easy as the OE exhaust. Had some L brackets lying around, reshaped them, and bolted them onto the valve slot.

Thanks for all the supplied insight FISH22. Community thanks you for it I am sure. To your point -- definitely a fair amount of adjustability that will be infuriating for some but it allows a fair amount of tweaking which we find necessary to have for various reasons.

Couple specific points:

1. Rotating pipes typically resolves pipes hanging low and or different levels on either bank of tips.
2. Also note the hangar placement/orientation in the instructions (not fully 90 degree) as that will assist in bringing the exhaust upwards into the body in general.
3. The valve spring may require some light tweaking. It's briefly noted in the instructions but ultimately the spring should be compressed once installed and not fit loosely. If it does fit loosely, it needs to be spread apart a bit is all so there is tension when installed. Seems to be some minor manufacturing tolerance variability in the OEM fixing bow/spring (PN #18307620323). Have been using the same spring for a long time and while rare it has come up on occassion hence the inclusion of the note.

Has anyone with this installed experience any valve rattling? I have fiddled with the springs quite a bit, vertical (stretching) and horizontal (twisting) to put more tension between the controller and valve top slot, and to better align the valve when it's in closed/comfort mode. It's mostly on cold start, but I do sometimes hear it against walls while driving. Seems to be mostly the left valve.

I even ordered two new springs to start from scratch.

Is the rattle quite distinct? I haven’t noticed anything out of oridinary but I’ll listen a bit closer at startup. The shop did have to tweak the valves a little as one side wasn’t fully shut at idle but after they tightened it, it was ok.

You can definitely hear it during cold start, and occasionally when driving against a barrier at certain throttle loads. And my left valve was the same; had to be tweaked a tad to insure it was closed all the way.

The Dinan support team is great and has been a huge help. Worst case, I do a one for one on the rear section.

I have a single midpipe as well and usually have valves closed on the highway. It’s too quiet but open is too loud. Is it any louder than stock with the valves closed now?

Definitely louder than stock, valves closed. More base and just a really nice deep sound.

[Dinan_Engineering]

Still unsure which Dinan G8x exhaust configuration is right for you and have queries you need answered?

Is the deeper axle back tone enough? Is there adequate extra volume, and/or an undesirable rasp introduced, with only the X-pipe? Is the full system just too much awesome to handle? Put on your headphones, sit back and prepare yourself for nearly three minutes of sensory magic to help you answer those questions and find your goldilocks setup.

Initial post updated to include the additional video as well.

Fitment was good but issues with tightening the outer tips proved difficult. Had to mount, then mark where to titghten, then drop the exhaust a little to make room to tighten. It actually took longer to mount the axle back than my original system all together! Lol other than that I like it so far. Has a deeper tone but I’ll get more time in the car this weekend.

As for the silver tips, I’m on the fence. They’re definitely shiny and the reason I went with silver was to match the wheels coming in a few months. But who knows I may just get the black ones later.

A few pics and some revs in sport+

Do you have a valve controller on your setup? I just installed my dinan mid pipe and rear section and seeing my valves only open 30-40% in idle/M1. I know this is due to not having a controller to fully open them but, just want to gauge how much yours opens since, in the video it looks >50%. I could be wrong though.

No valve controller on mine. I’m pretty happy at how loud it is at idle and on the throttle. Any louder would be a little too much 😂 difference might be that I have midpipes from TFL that delete the cat and resonators so that may be the reason it sounds louder.

I had the x-pipe installed few days ago. It transformed the sound of the car to what it should have been from the factory. No drone and easy to live with almost stock when the valves are closed and deeper tone with more pronounced bubbles when the valves are open. Very satisfied with the sound. The installation was done at the dealership.

Real dumb question since, I had my exhaust installed at a shop due to limited driveway and garage space.

How do you access the exhaust tip clamp/bolt for tip adjustment? I removed the rear defuser and still didn't have enough room from the rear with a socket wrench and/or wrench to loosen the clamps.

Or is the only way to drop the whole exhaust but, this does not make sense since the instructions has you install the tips once the system is mounted.

Thanks in advanced!

Access for adjustment of the clamps needs to be done from the bottom/backside of the tip so you would need ramps at minimum. From that position its just a socket with an extension. Not able to do it from the direct rear that I am aware of although I am sure someone has probably found some ingenious, although probably sketchy, way of accomplishing the task.

I love sketchy.

I’ve found a ratchet wrench to work well too. Small turns, but it works.
