Not too loud per se, but possibly too much drone.
True, I was going off sound clips. If it’s too much drone, I can swap out the LDP to another aftermarket pair that are resonated. Thanks for the heads up. Once the exhaust comes in I’ll give an update

Yeah, interested to know how it works out with MR LDPs and FI non-resonated CB. Please do report. The MR LDPs with my non-resonated Stillen CB was unbearable around 2k RPMs. Swapped in resonated HKS LDPs and barely helped. Added some in-line resonators into the Stillen mid-pipe and helped a lot!

Is this the brace you removed for the rattle. I have a slight rattle under harder acceleration after my mr downpipe install

Correct. Most of us have clearance issues with that brace with pretty much any aftermarket CB you choose. I ditched my brace completely. But maybe the smarter thing to do is add 1/4" - 1/2" spacers to increase clearance.

Just use the spacers with longer bolts.

I used spacers on my cross-member to add a gap between the exhaust piping and no rattle problems. Don't know if that is your problem though. It is simple to do to eliminate the known rattle problem if the cross-member is touching the exhaust piping.

So I got my Invidia Gemini catback installed. Along with Megan racing LDP. All I can say is, I understand why @Jonjostar disappeared, I've been taking every opportunity to drive the car. Thoroughly enjoying the set up. Beautiful tone, no highway drone at cruise speed ~ 115 km/h... feeling the torque gains too. o_Oo_O

Hi. Does anyone hear a nasty rasp around 2500 rpms ? I know OP said he didn't have any. But I hear it everytime, at upshifts, downshifts. I have it booked to the MBRP 3" exhaust on q50 red sport

Ohhh okay okay. I guess that's just how it is. Is there no way of reducing the loud rattle rasp ? It's pretty obnoxious.

I'm just curious, but I'm not sure what rasp sounds like. Can anyone describe the sound or link me to a video of it?
