H pipe exhaust valve
I currently have the non performance exhaust option on my car and the secondary cat delete for the last year my h pipe valve has squeaked every time I started or revved the car past 2k in sport plus or race mode. I have taken my car to 4 different dealers to have it fixed and all 4 of then said that they fixed it but they never have.
so my question is can we get rid of that valve without causing a cel or low power mode because of it being gone. i would rather not have my car get quieter every time I put my foot on the brake because of the valve anyway it also causes my downshift in sport mode when I'm on the brakes to be extremely quiet.

AWE replaced the complete section under warranty and supplied a valve simulator for the H-Pipe harness.
I am still running no valves just simulators with no issues.

So has anyone tried to swap to a x pipe or just a straight pipe to remove both h pipes. I only saw one aftermarket exhaust company using a x pipe on our cars and it was ipe. How would that effect sound.

I had the same issue with my AWE Track Exhaust. My h-pipe was squeaky around 2000 rpms. AWE wanted to fix the problem but I decided not to take it off my car and have them send me a valve simulator for my h-pipe. Now the h-pipe valve will stay open 100%. I put it on today. Car is making great power, but i feel like the car is now quieter in the low end but good up top... Did you experience anything like this ?
Thanks

I haven’t had a h-pipe valve now for a long while.
I have Vibrant Gesi UHF catted downpipes as well as the AWE Track Edition Exhaust and mine has a deep throatness about it.
