HMS 1M exhaust update?

E30 Racer · 10-09-2016, 06:36 PM

For those of you with this exhaust, what's your experience been over time? Any issues? Has the sound changed? Has it remained drone-free in "silent mode" (with the valve closed)?

I picked mine up second hand earlier this year and have nothing but praise for it. Sounds ferocious with the valve open, and similar to stock when closed.

I do find there's a touch more drone than I had with the previous Remus with the valve closed, but it's only a slight resonance.

Thanks P_Monkey. How would you say your HMS drone today compares to that of the stock 1M system? Are you catless from the turbos back?

I only drove my 1M around stock for a few days before the Remus went on, so it's hard to recall. From memory the HMS is better than the standard system was.

I'm still running stock DP's, in conjunction with N55 mids and he HMS rear section. I'm sure this would help with the drone as well.
