Thanks.

The rasp mostly comes from the midpipe

I bought non resonated DP's. They sound Good too but resonated will always sound a little better. But the fitment on the ARM was Trash. They should not be in production tbh

That was all i needed to hear, are your mid pipes resonated? Might just pay for the AR Design ones then and get resonated mids as well.

M Performance Mid pipe and Muffler with Stock Secondary Cats in place. I just may add resonators myself as well. Plenty of space to do so....

I reached out to arm, i showed them this thread as well. They stated they had no fitment issues reported. They also said they verified fitment on their project car and a few others before they started selling them. I asked, and they told me they would provide a full refund if there were any issues. So far the pre-sales has been very responsive and helpful. I plan on purchasing these primarily because I want the resonators. I also do not DD my car and I have access to a lift with the ability to leave the car out of commission if I do encounter any problems. It will likely be 1-2 weeks before I am able to order and install, but I will let you guys know how I make out..

Looking forward to seeing your feedback/thoughts and hopefully video/sound clips. I'm waiting before I pull the trigger.

weird, the aluminum underbelly is fairly far away from where the DP meets the exhaust at the flange, im having a hard time understanding how you could be hitting that.
