I was just curious what the best route to go for exhaust would be?
I want something quiet and not noisey as hell like my current cat-less setup. Right now I just have the stock exhaust with gutted cats and the sound is starting to bother me, i'm not the kind of person to have loud exhaust at all, it bugs the crap out of me while im driving, but I don't know if it is just loud inside the car, but if it is as loud as it is outside it's wayyy to damn loud.

Anyone have any suggestions for a quiet exhaust that will still get me a lot of flow for the best price?

oh, forgot to mention, I have a GSL-SE, so i still need to keep a little back pressure.

 

Duuuude! No offense...but this question gets asked every week!

Racing Beat is the best all around..a wee bit expensive...but good quality.

Worth every penny, great sound too.

 

yea but its not emissions and state legal everywhere, right?

 

i'm in texas and they are pretty liberal about exhaust. I'd go with RB aswell. I don't have it yet but I will have it soon. I've heard nothing but good things about it. Also aslong as you know someone at an inspection place getting tags shouldn't be too hard.

Oklahoma doesn't have emmissions tests anymore, so I don't care if it is smog legal. I just want something that is quiet, and I searched for a thread for someone else looking for the quietest, best flowing exhaust but I didn't find anything.

I know racing beat is good, but is it quiet? I don't want a lot of noise.

 

unfortunately alot of high flow exhausts aren't that quiet. They'll still be quiter than your current stock exhaust. I guess the real question here is how quiet do you want to go. you can always put on high flow cats and put on a muffler that will give you the back pressure, but it won't give you as much flow as a strieght high flow exhaust kit.

do a nice systeme thats actually not that expensive

I'll put in my word for RB. I've been nothing but happy with them.

 

Racing Beat is an excellent compromise between exhaust flow and streetability, (quitness). You will love the exhaust note to the point you won't want to hear your stereo anymore, lol.

 

I have heard a few sound clips of people that have RB exhaust, and it does sound good. I guess thats what the "Streetable" exhaust would be? I never quite figured that out.

 

Do yourself the favor and just buy the Street Port exhaust. It's got a nice low tone, but barks when you stomp the loud pedal, but it's not ungodly loud...it's right where you want it.

 

yeah, racing beat rocks!!! It's not obnoxoiously loud, like my cousin's 240z, and it's not so quiet that you can't even hear it even when you want to. It's a great setup, a little pricey, but you get what you pay for!

 

the mindtrain setup is good too, if yuo can find a used setup, because they are out f production

 

I could argue that this is not true. RB is good if you want a quiet exhaust that doesn't flow. A muffler that is effective enough to quiet the rotary that much can not be a straight through muffler. Also, the pipe size is not the greatest. 2" pipe is kinda small if you ask me. But hey, thats just my opinion. It is possible to make a 2.5" exhaust quiet and cheaper than the RB system and end up with more power. Use a large magnaflow muffler (the big 5x8 ovals, at least 18" long), then a "fart cannon" out the back WITH a silencer in the tip. I actually had this with 3" pipe and it only hit 98 dB outside the car at 3000 rpm.

 

I've got the full RB streetport exhaust, and it's nice... Sure, it's louder than stock, but it's nice and mean sounding... It's perfect as far as I'm concerned.

 

Why would you need such a large pipe on an N/A setup?
I've always been told not to EVER go over 2 1/4, or you'll not gain as much, or something in better wording.

It's nice to have fart cannons that are quiet, but I don't see how they could make more power than a properly designed, application specific exhaust.

Now, I'll agree that the presilencer you get with the setup is damn near useless, just have a shop custom fab a 2" pipe from head to tip like I did

 

I'm not saying use a 3" pipe like I did. All I'm saying is that its possible to make a rotary quiet without having to shell out nearly $1000 for an exhaust system. 2 1/4" pipe would work just fine and probably make it even quieter than my exhaust was. I'm just saying what I think, and I've had personal experience with this stuff. I found no noticeable difference from switching from a 3" pipe to a 2 1/4" pipe. Hell, 2" is probably fine, but to me that seems somewhat small for how much a rotary flows. Also, using the mufflers I mentioned worked excellent in my application. With the silencer in the tip of the N1 style muffler I have, the car was quiet enough I could still hear the fan over the exhaust. With the silencer removed, it was noticably louder, but had a deeper tone than the RB systems I have heard.

 

Okay, so I pretty much know I am going to get the RB exhaust, but which set?

The "1984-85 GSL-SE RX-7 High Performance Exhaust System" is cheaper, but what is the difference in noise and power between that and the "Street Port" setups?

I want which ever is quieter, that's all I really care about, I will comprimise power for noise.

Thanks again

 

Get the streetport exhaust. Why? Because yes, it's more money, but then, when you eventually kill your motor, have it rebuilt and streetported, you'll have the right exhaust.

I have a bone stock 12a in my car right now... But I have the full streetport exhaust system. Do it right the first time, and you'll end up saving money.

 

SPAM! This is post #15, re-written to sell some kind of adapter cable. SPAMMER.

 

I had the "rotten-egg" smell in my 85 GSL-SE back in 1999 and bought the Bonez Street Performance system from RX7.com which is "plug and play" and mated with my stock muffler and I was very happy with it. Fast-forward 20 years to 2019 and my original stock muffler was starting to rust around the surface where the tips are welded and needed to be replaced. I figured as long as I was going to replace the muffler with Racing Beat's Power Pulse muffler I would at the same time replace the 20 year old exhaust system too (things for our cars are not getting any cheaper, and in some cases are no longer being made.) This way I will never have to screw around with this issue again in my lifetime (I'm not getting any younger.) The original system in 1999 was $245.00 plus $15.00 for the gasket set, the system in 2019 was $311.00 and $15 for the gasket set, now they are going for $426.21 and the gasket set is $25.00 which proved my point of doing it when I did. If you pair it with the power pulse muffler it's $858.21 not including taxes,

Does Ari even have that set up ? I have called twice in two years and he no longer carries things on that website. I want that bonez set up with a PP muffler at the rear. I don't have a air pump so people say my cat will get clogged ( mine isn't ) but the resonator by itself is too loud .
And before any one says to go back to stock , the 79 has a thermal reactor , i can't add a cat with the air pump without completley retrofiting a 81+ cat system and I know people who run headers with cats etc.

 

RX7.com shows 1981-83 12A system, and the 1984-85 13B systems available.

 

I installed a Road Race header and was going to install a Magnaflow muffler that I bought ......just before I sold her😪
