Never heard of this company, wondering if anyone has tried or heard of them.

Thanks.

The rasp mostly comes from the midpipe

Yeah because most are non resonated, I am thinking of doing this and a converting my mid pipes from non res to res.

Appreciate it, seems like the e90 community didn't haven't fitment issues.

Tried. They fit like Crap and hit the Aluminum underbelly. Luckily I bought them used. They did sound good though. Not much rasp.

Are you still running them? What did you have to do to make it work?

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.

Its usually a hit or miss with this brand .. I would pay an extra $100 and get a VRSF downpipe

[f82george]

It's close to it and it only will rub when they get hot after a few pulls or so .i believe the expand from heat a bit causing it to hit

I'm specifically going with arm due to the resonators. I'll let you guys know how I make out.
