Downpipe length
I want to do ASR controller and secondary cat delete on my new (to me) car as a quick/inexpensive way to get some sound. I'm just wondering if I'm not pleased with how loud that setup is, do I still have the option of running a downpipe after? Essentially...will the bottom of a downpipe connect to a portion of the exhaust PAST where the secondary has been cut?
Also, would a race catted type downpipe be much louder than a factory setup with a secondary cats deleted out of it anyway?

I don't think I want't to go catless down pipes or down pipes in general, I just want louder, but wanted to make sure I still had that option of I chip out secondaries. I think secondary cat delete and awe Track exhaust would do it for me but I'm wondering if you can even do an awe Track exhaust on a 2017 when it appears like some 2017s were going into limp mode using the valve simulator, because you need to use the valve simulators with the track exhaust if your car came with performance exhaust.

Cattless> Race Cats>> secondary cat delete> stock DP's
Can't comment on the aftermarket exhausts though -- have never heard them in person. If you have the PE, though, I don't see any reason for the aftermarket exhausts...
I haven't kept up with the valve simulators, but when we were initially testing them on PE equipped vehicles, we didn't have any issues with limp modes or reduced power modes.

I can barely even hear my PE exhaust with windows down. My friend has just awe Track and its much louder. I don't think the asr module will do enough to even be half as loud as the track exhaust. Maybe asr + secondary cat delete might compare to it.
From the what I've read, simulators worked on all 2015 and 2016 cars, but I read a thread where 3 separate people had issues with the simulators on their 2017s. So I'm not sure if I could even run the track exhaust because of this.

Been debating a AWE Track exhaust as well but lets see how this goes.

for the ASR install you dont have to keep your keys at a certain distance etc do you? Just pop the trunk and install there and then?

Reading through a thread about the valve sims it appears like 2-3 people with 2017's had that limp mode happen when they tried the sims. In that thread none of the 2015/2016 reported a problem. It also appears like they followed the install instructions correctly and tried a few times. Since we need the sims to run the track exhaust if we have PE, I'm wondering if 2017s can even run the awe track exhaust.

youll never know if you dont try. Even if you get a power issue its not the emd of the world, just a software thing that the dealer or amy shop with the right tool can reset

Of course we can. I put a awe valve sim on my h valve and had no problems. I didnt even follow any instructions.

I'd rather put the 5-600 CAD that the ASR module would have cost me towards a catback anyways.
