Been looking for a dual tip exhaust for my '92 Efini FD, and right now I'm tied up between the Racing Beat Dual Tip or the APEXi N1 dual exhaust. N1 looks better in my opinion but I'm worried it'll be too loud. Any other suggestions or experience with either? Not going with a single tip because they really don't seem to sit right in the bumper, just my opinion. FD has APEXi PowerFC ecu, Rotary Performance non-resonated midpipe with a Denso fuel pump and stock injectors. Makes 286 at the rear wheels at 80% max injector duty.
There's at least one more that I see pop up on rare occasions. It looks to be more of a true dual but probably pretty loud. And from the pictures I've seen of it looks to crowd the rear valance and/or require trimming. I just can't remember the name. Edit: St. May’s DT. —-> https://www.rx7club.com/3rd-generati...xhaust-949165/
With your midpipe and a desire to keep things tame I think the RB DT will be the way to go.
There's a guy selling a twin tip M2 exhaust on this club.
Unicorn-rare these days and on par with Racing Beat.
I agree, I have a M2 Catback with a High-Flow Cat (I think it's M2 also) and it's not really that loud compared to other exhausts, probably on par with the Racing Beat.

I sent the guy a message about the m2. I think that's the exhaust I'm going to go with. Thank all of you guys for the input
Even more unicorn than the M2 is the St. May Shotgun exhaust if you can find a used one. St may went out of business a while back. Looks like a bigger Dual N1, but it's comparably quiet as the RB Duals.
I went from HKS Silent Hi Power to Racing Beat Duals .... it went from 83 dB idle and 95 dB WOT to 68 dB idle and 79 dB WOT
I am on twins with all bolt ons, power did not change.
I have several exhausts at home including the St. May, I would not call it a quiet exhaust. It is called the shotgun exhaust after all. I have not run it with my resonator though. I do not have a RB to compare to but I’m now running Tanabe medallion and it is pretty quiet. I’m happy with it.
Never heard one in person and it’s a cool design. But in the pictures I’ve seen they look to crowd the rear valence and sometimes not exactly level.
Jim... I think so many after market cat backs cause the bumper to melt that I would recommend that anyone who installs one put on one of the heat shields available. Either aluminum or carbon fiber work.
I recently swapped the st may back from RB duals. Sounds the same with the resonator while driving it around town. I enjoy having music while driving even with just my door speakers. I'll record a new/better video soon. Here are some pics from last week.
Only draw back with these is weight. Wish I can find a shop in CA to replicate these in lighter material.

RB DT doesn't melt the valance or bumper. Neither did my Greddy SP. Maybe because they were both double-wall tips. Maybe true if I had one more rotor cooking up front. Sadly that's not the case on my car.
I'll let you know if the deal on the M2 falls through man. It might be easier to sell to you if you want to meet up though I'll be making my way to New Orleans in 2 weeks.
Wanted to make a note here that the "M2" exhaust is still available new, just not from the defunct M2 outfit. HiTech Exhaust in Sydney, Australia made those exhausts from M2 back in the day, and they're still in business. After deciding I wanted a M2 and couldn't find one used, I went straight to the source and they had a "M2" FD exhaust new on the shelf that they shipped to me - they also said they have the jigs still in their factory so they can make them new to order as well. If you don't mind the shipping cost, give them a shout and see if you can get one made for you.

I've been thinking of doing the same. I was going to work with a friend's shop in the Bay Area to help me out with this, but I ended up putting it on the back burner.
