Swapped in RB Duals in place of Greddy Ti .... so much less drone.

Car actually feels slower with less noise so I can go faster now!

 

Car had blue aftermarket toe links when I got it. Also clunked like hell from the back since I got it, even after new pillowballs. I've heard the bushings in the aftermarket stuff goes bad fast, so I ordered four new ends or heim joints or whatever they're called for the aftermarket links. $$. Figured that would be good to go for a while. Swapped out both ends on pass side toe link where all the noise was.

Fixed! For about a drive around the block. Then clunckckckcklunckckcklunk... Made no sense. Checked tightness, still there. Figured it must be something else and was poking around at other things for a while. Still, why did the noise go away for a bit when I messed with the link...?

Remembered previous owner(s) had kept almost all the stock stuff and passed it on to me. There is a special place in heaven for people who do this.

Had they changed the stock toe links because they were failing, or just for some bling? Let's find out. I swapped in the pass. side stock link.

Quiet as a mouse. And staying that way.

Say it with me everyone.

"Demods are my favorite mods!"

 

I have noise... Notice it when the car settles after breaking to a stop. I have to try this de-mod!!

 

I just got mine and it's bone-stock. The only complaints I have right now are:

1. Yeah, I've driven a modded RX-7 before. My car is slow.
2. It's also way too quiet. All I hear when I stomp on the go-pedal is more tire noise.

So, as much as I'm trying to keep it "concourse-ready", I'm probably going to go Racing Beat catback and whatever-downpipe (I think Montego recommended something to me in another thread already). Hopefully will provide a little oomph, but I don't want to start going crazy.

I've been down the road of "more mods, more power, more pain" before when I used to be big on 2G DSMs. So, no polyurethane bushings for me, no huge intakes/turbos/fuel injectors/engine management/etc. MAYBE a stock R1 strut tower bar (do those actually help much or is it more placebo?) but no aftermarket coilovers...although Ohlins are nice, I know...

 

A strut tower bar will solidify the front end. Definitely not a placebo.

 

I used to have a bunch of exhausts ranging from HKS carbon TI, Apexi GT spec (Loudest), RB duals and now Apexi Noir.

At first, having a loud exhaust is cool. Then it gets annoying. My Apexi Noir is very quiet, even more quiet than the racing beat. I"m now 34 and I guess I"m over the loud exhaust.

Sometimes I want to drive and be an adult?

 

I'm 41, we're all adults here. I'm not talking about wanting a LOUD exhaust. I don't want everyone to hear me just cruising along and I certainly do NOT want drone. But, when I stomp on the pedal, I expect to hear the engine. My Boxster is a great example of this--it's civil as a Camry, until you are accelerating, and the exhaust isn't valved or anything like that either.

So, since I have your attention, how loud would you say the Racing Beat exhaust is?

 

I had a chance to drive a base Jaguar F-Type this week. What a beautiful car! The base car has a 340 hp supercharged V-6 which isn't that powerful, but you should hear that exhaust when you get on it raspy, roartry, and ultra gurgly. It's awesome! Not what I expected from a Jaguar. Great fun.

 

NI passed adult about 40 years ago and back into second childhood.
Not much to compare it to, never heard the stock catback. But fwiw it's a little sharper with little to no droning like my old GReddy SP.

 

I had a GReddy Ti on the car with a RX7 Store resonated midpipe and it wasn't too bad, but it definitely droned. I recently switched to RB duals and I LOVE the sound now. It almost reminds me of a supercar under acceleration. And it doesn't drone. Not quite as loud as the GReddy.

 

You are quite the gifted child, then!

Thanks for the input, I'll add the Racing Beat exhaust to my "to do" list then as it sounds like the right balance to me.

 

One of the best sounding exhaust for our cars in my opinion.

 

I love the look and the volume of the RB dual but let's be honest it doesn't sound very good.

I think the best overall sounding basic cheap FD catback is the PFS BUT they don't fit very well at all. Serious PIA to install.

 

OK, let's be honest and all. I think (from the inside and outside) the RB DT sounds better than a GReddy SP, and WAY better (from the outside) than a half dozen or so who-knows-what-brand cat-backs that I've heard over the years that sound tinny and unnecessarily loud. It doesn't drone, flows well and looks awesome. The only negative I personal know of is that it's marginally heavier than at least the GReddy SP and probably most of those other cat-backs with single wall, grapefruit shooter sized tips.

 

...and for me, PFS was not a pain to install. Maybe they had different production runs.

I like it, but it does not have the stock look ala RB

 

LOL.... anyone knocking the greddy SP1 sound can't hear. That's my second favorite.

Or maybe I can't hear, too many track days and attempts at playing guitar

Anywho not a fan of the sound of the RB single or dual. YMMV

 

Unless your midpipe hangs low which usually means angling the DP as far down as possible it wants to cook the rear bumper skirt.

I can't remember the last time I bolted up a PFS without having to do some adjustments and even then it was too close to the skirt.

 

I'm not sure if I've ever heard a GReddy SP1 but I like the sound and looks of the RB dual over the GReddy Ti. The only downside is it's way heavier and I would imagine doesn't flow as well.

 

YEP anything sounds better than the TI unless it's at WOT and then that bitch is nasty.

It flows so good you'll likely see a 2 psi jump in boost just bolting the thing on LOL

RB is a flow restrictor which is another reason it's quiet or has just a hint of that stock muffler vacuum sound.

What you sacrifice in sound and flow is made up for with tasteful looks or it's a nice street exhaust.

 

There's another advantage to it being a not a completely free-flowing exhaust--whenever I am tempted to up the boost/v-mount/single turbo, I'll have folks saying "aw man, but you have the wrong exhaust!" and then I'll be all "dang, I already spent money on that. Guess I won't turn it up!"

 

LOL......... so true and I like your attitude. A daily driver/weekend car isn't a race car. This car is perfect with twins making 300 rwhp. It is Just a super fun all around car at that power level for running around on public roads.

I know there is tons of love for the RB and I have one on my daily driver but as I said before to my ears it is not a good sounding cat back. Not enough pop and growl etc...

That said I'll take it over an N1 or any other loud droning exhaust which is pretty much every high flowing exhaust. It's all give and take. The PFS for 500 gives the most and takes the least regarding sound but fits like **** and burns your skirt.

 

Weird, I've owned maybe four PFS over the years. Fitment was always drama free, although the burned upper skirt is a potential side effect-agreed there.

Maybe it's been mentioned before (probably by me, lol) but for cars making upwards of say 350 rwhp the RB dual tip absolutely robs power. A buddy with a single turbo at ~400 rwhp lost a solid 20 rwhp moving from a turbo tuff exhaust to the RB and then switched back. Looking at the piping diameter and bends it's not surprising really.

 

I never had fitment or skirt burning issues with the PFS when my car was twin turbo, and that was years and lots of track time.

I went backwards. I put a Greddy Ti on because I wanted more nastiness relative to other cars at the track. My car seemed too tame! Even on the street these days the new mustangs and camaros are growling and popping, but they are quieter at idle at a light. That's tough to achieve with our cars.

When I went single it seemed like the PFS wasn't appreciably quieter so I just put the Greddy back on.

The RB I just couldn't do. All the work and expense to build a free flowing car, I'm not going to put a cork in it at the end. If sooner have some triple muffler custom MP/CB made that has free straight bend and large tubing with more of mature tip treatment. In fact, that's not a bad idea. Design it myself.

 

I could write book on trying to hang that effing exhaust properly. It just wants to sit way too close to the car. It doesn't even need the rubber donuts 1/2 the time because it doesn't hang from the bottom of the car it holds on like a tic. Rarely had one mount up easily or hang where it should.

Then again maybe it's just me and my exhaust hanging skills

Pete your PFS was 10 years old with thousands of track miles. In other word that bitch was burned the **** out. It had zero insulation left in it LOL

Yes the TI rips on a single turbo FD

 

So it's not supposed to be that loud

Kind of like it though and it does flow
