Yeah I got it for the look/ sound. It’s really quite though. Almost too quiet. You can’t hear it at all cruising at highway speeds. It’s slightly louder than stock. Looking into a catted dp in the future. It does crackle a lot as is which is nice
I do want to customize a cat back exhaust that will look good but not loud. I have Catless, no luck with any catback in the market.

I have the defouler, but I'm not using it because I have hondata to cancel my check engine light. My car rarely crackled with the stock downpipe, after switching to an aftermarket downpipe it started crackling.

The install was not too bad, had couple people help me out. I want the PRL cobra intake it's the best out rightnow. With my 27WON intake it's usually all over the place with IAT around 20-30 ambidient temperature to outside. PRL cobra keeps it really low around 10-15 sometimes even lower.
My car crackles when I shift at 1,500RPM, and also I’m second gear when I downshift low or simply crushing in second gear and letting off gas in the high 1,800RPM, I get crackle all the way down to 1200RPM which is nice. Last like 5+ seconds in stock cat

Think I am going with 27won Drop in turbo upgrade and their dp/fp combo. Keep my PRL cobra and get PRL FMIC.
Probably the FMIC first to get it over with so my car stays nice and cool with the new gains from Turbo/FP/DP.

Blah and a new clutch before the turbo / FP/DP. :doh:

Okay I know this is crazy, but I'm going to tell you to not go 27WON dp/fp combo.. Here's the issue that I just figured out with one of the instagram guy with the 27won catless downpipe. The fitment of this downpipe creates a little bit of gap on the heatshield causing excess heat shooting temperature up. First picture is my catted downpipe and the second picture is one of the instagram guy's catless downpipe. As you can see, there's a slight gap that doesn't cover the entire downpipe and from that gap it's shooting ridiculously hot air to the plastic part of the intake. This is the companies design not having the correct fitment when other brands do cover it. The 3rd and 4th picture is an example from one of my friends RV6 catless downpipe. It actually covers the entire downpipe part not causing heat to come out. 27won stated their heatshield does have fitment with OEM parts, but definitely it's not true.

I would just wrap the DP with DEI titanium heat wrap and seal it with DEI silicone heat spray.
It keeps the heat within the dp much better than that medal heat shield..
Or you can wrap and heat shield for best performance.
RV6 has ceramic coating option, its same idea except its ceramic coated to begin with compare to heat wrap after ward.

Exhaust, Ktuner, flex fuel. Next weekend, I’ll be installing intake, intercooler, and downpipe.
Same as me. Experienced clutch slip for the first time the other day in 4th gear at 3500rpm. I won’t be adding more power without a clutch

I have no idea...... All I have been hearing about so far is FX350 or 400. I dont really know that much about it. Havent done much research on what the best option is. First time being in the market for it.
I’m going to wait for more options.

Many seem to be waiting for Exedy, or something from Action Clutch. Eman is also fabbing up Type R Clutch conversion kits to work in our cars, and plans on selling those, which I'm very interested in.

Guessing they will have to redesign the part, and/or give existing customers free exhaust wrap

On a related note.... I'd like to thank all the early adopters for testing all the new mods being released for the 10th gen platform. They're the real MVP's. "Taking a chance, risking it all, for the thrill of the moment."

I break in my clutch, or car in general, pretty well so I’m hoping that has help it reached this point. Only time will tell when I installed those parts. I’m expecting no more than 220HP at the wheel so I don’t think clutch would slip. Ktuner +6, wish there was +9. My main mod is just downpipe and intake as well a flex fuel with Ktuner, shouldn’t be more than 60WHP imo
