Bring Challenge X-pipe's back?

Pairing it with a less than 500 mile MPE v2.

Don't get me wrong, I think the MPE sounds great but I was extremely motivated to enhance the sound. Mostly because I had (and still have) one of ACM's modded cans. I know people are +/- on the "quality of sound", but I thoroughly enjoyed it. HOWEVER, adding a x pipe would have been absolutely over the top for me. LOL.

So, after listening to a few YouTube vids, this appears to be one of the better setups with minimal rasp. Now granted this is a "re-make" and who knows how it will sound.

Below is the vid that inspired the purchase.


If it's a hit...I will list the ACM exhaust (excellent condition btw); OR, I might move to sell the MPE and go a different direction.

Stay tuned.

Did you get this installed yet? Any feedback?

Would the sport pipe here be a way to accomplish this? And will it bolt up to the Dinan?

Haven't you gotten the car tuned? The fuel smell is extra fuel that the DME throws in to cool the cats down. Eliminate the cats, tune out the CCOT (catalytic converter over temp in most tuning courses), smell is drastically reduced or gone.

Installed mine last weekend. And after driving it a few times all I can say is it is perfection for what I was looking for. Same aggressive sound I had with the MS race but at a more tolerable “grownup” volume level. I will try and pull some video/audio over the next few days for your consideration.

Yes - below is a 7 sec clip the shop captured during the last pull.

From my perspective, the Sport X pipe is a phenomenal piece and it exceeded my expectations: "nice" gains (352.9 hp : 272.9 tq); very faint smell; superb craftsmanship; ~ 15lbs weight savings; no vibration at idle.

As mentioned, it's paired with a MPE and sounds awesome; just a bit raspy over 5K, but not terrible. It's a DCT car and the downshifts are wicked AF!

Can we get some sound clips with MPE?
If so, an exterior with a few different drive by say varying rpms.

Personally I wouldn't bother with mics connected to the rear because no one experienced that perspective in reality.

Wanted to thank the community for supporting a great product! The SPORT X-pipe is selling amazing and we only have one left. I'll be starting on a new batch now.

We also just completed the install PDF guide.

yes - i have a custom tune and the goal was to keep HP in a "safe range" while optimizing TQ. Definitely pleased with the results.

If I have test pipes and Stage I tuning now do I need to change my tuning? Or I can use my current tune with these sport pipes?

If you have test pipes you should have a stage 2 tune...

Should be the same tune for both setups.

Yes please, am interested in hearing it. What exhaust do you have it paired with?

That's correct. Test pipe tune will be the same tune needed for the Sport and RACE X-pipe.

Woah just seeing this, I guess I got lucky! Cat told me there was one left, good thing I snagged it yesterday 😁

Going in this week! Just need to pass state inspection first :

[k_mann]

Alright so I got mine installed and it sounds absolutely AMAZING! Craftsmanship was excellent as well, I ran into one issue with one of the o2 bungs being slightly off center from the hole in the pipe (i'm talking like 1mm). But it just prevented me from hand threading up snug like the other 3 since the sensor just BARELY grazed the cut out. Not really a huge deal since it went in straight, but I relayed this to IND so I'm sure RKP will be aware in the next run.

That said, I didn't thoroughly watch all the tips and tricks on x pipe installs and got some heat shield rattle, at least I'm 99% sure thats what it is, haven't got back under to look. Only happens once fully warmed up and under 3k rpms with heavy throttle, so like talking off or gassing it a tad without downshifting.

I need to check my clearances but anyone have any tips of what areas I should check? I know its common to hammer up the heat shield where primaries used to be and near o2 sensors, but wanted to know if there was anywhere else I should check?

Add a Karbonius airbox to that and you'll have a setup very similar to mine. The sounds are glorious.
