Just ordered the ModalWorks Downpipes for my FL coupe. I went with catted version so no tune required. I’ll post videos as soon as I get them installed.
I already have the ASR module installed so I am hoping that this really opens up the sound.
I have their catted downpipes, after 500 miles no CEL
Oh Nice. Is yours FL or pre-FL? Can you give me any info on what to look for? How much increase in volume? Any increase in pops and bangs? My FL does pop and bang but you really have to drive aggressively.
I have the Face Lift, and to be honest I did not pay attention to how loud it got, but definitely sounds a lot better and has more pops and bangs. I also have an aftermarket cat back system so I am not sure if the changes for me would be the same for you.

Thanks for sharing! Did you have them cut your OEM DP or drop the transmission? I think the emission testing is similar in CA and AZ; do you know if the 200 cell Sport CAT is enough to pass emissions there? I’d rather have shops just chop the OEM to install the new DP and not have to mess with the transmission, but of course that’s a horrible idea if I have to pass emissions down the road haha
The shop told me they will only cut it because it is safer. I looked up before I did the down pipes and if I remember correctly they said it will not pass the visual inspection, but you do not need to do a smog test until the model of the car is 8 years old.

I should have it installed next Tuesday. Will definitely post videos.
Nice, what I like about this idea is that you don't have to get a tune for the catted downpipes you are getting. For me personally, I just want to improve the sound the car makes without having mess with tuning the engine.
Curious to know when you get the downpipes installed how the car sounds when reving and also if it improves the throttle response and reduce turbo lag even further.

Exactly the reason why I went with Catted DP. I am sure I will tune eventually but then I’ll end up going upgraded turbos at the same time.

Sounds amazing. Do you get the gear upshift burp or brap as well with these downpipes? The facelifted cars do not have that from factory.

DP’s just came in. Going in tomorrow for the install. I am also doing before and after Dyno just to see if there’s any difference. It’s a fairly low reading mustang dyno. My F90 was around 560 whp on this exact dyno. Different day different results but they do apply sae corrections.

Are you going to put the car on the dyno, get a few stock readings, then install the downpipes and re-dyno right after? Definitely interested in seeing if there is any improvement without a tune. Most dyno sheets I have seen only show the difference between a car with downpipes paired with a stage 2 tune and a car with no downpipes and a stage 1 tune. It always had me wondering if the downpipes were the source of any of the gain or if it was just a function of the more aggressive tune.

Correct. Getting a stock baseline then installing Catted DP’s and then re-Dyno afterwards. No tune. Just curios to see what differences DP’s make on their own. Not expecting much but let’s see. I am mainly doing this for the sound.

Excellent. I do not expect much either, but it is still an interesting data point. I will be keeping watch for the results.
Yeah I'm interested in seeing the figures for dp's alone. That's the setup that I'm running. PS : just install o2 adapters and no check engine. I've had it this way for like 3 months.

Do we need adapters for the Catted DP’s? I am thinking no.
