Agreed, when the drone is very focused on a specific frequency, but in my case it's a pretty wide range.
Why are you confused? We tune other aspects of our cars, why wouldn't an aftermarket exhaust deserve the same attention if one isn't perfectly satisfied?
Exhaust note is highly subjective...
The UCC is awesome. Rogue makes good stuff too. But I would still consider the Auto Solutions setup - maybe even giving him a call and talking through whether his product would be an improvement over what you have (he's an honest dude).
Just my two shillings, of course.
I'm going to call vibrant tomorrow and get their insights too.
I want to reduce drone as much as possible without overly deepening and rounding out the tone. I happen to like a higher pitch overall, and even a little gnarliness.... So long as it's not accompanied by deafening drone.
Ordered Vibrant 1142 (Ultra Quiet) and 17950 (bottle) resonators which arrive tomorrow, and will see which of the two will fit in the space available. The UQ should technically be quieter than the bottle, but the bottle is much longer so it could be about the same. I bought both to up the odds...
I'm late to this thread...
Re: your M5's shifting experience not being where you want it despite work you've done to it - what work does that include? Have you done an Auto Solutions SSK? If you haven't, that could be your answer. Ronald's products are totally custom built to your application...
Decided to add a resonator already. Too much drone for my taste, but again, great sound quality when ripping it.
Going with a Vibrant 17950, in the midsection after the front resonator.
Nice! I'm planning on doing something similar with my new Remark setup, but not replacing a resonator. In fact I'm adding one bc I don't like the level of drone... Just a touch too high.
Then later I'll add a FMU megaphone to the front section right after the front pipe.
Got sound clips yet?
Installed a Remark SS exhaust today. It's a full 3" downpipe-back system (includes a high quality front pipe). Installation was very easy, with excellent fitment. The included hardware is decent quality zinc plated stuff, and the gaskets are excellent - nice and thick and the right compressible...
