getting rb exhaust! installation tips?
well, i finally got together enough money to buy the full rb exhaust for my 79. I'm so excited, i don't think i'll be able to sit through school the day that it's supposed to come! Anyway, I was just wondering if there were any good tips for a clean install before I got it.
Thanks!
Thanks!

On my streetport exhaust, where the header connects to the dual presilencer pipes, there were 6 bolts that I had to go back under to re-tighten after I checked for leaks. I dunno what system you bought, but if it has the 6-bolt setup there, I'd be sure to crank 'em tight the first time. The top middle bolt sucked to get at.

I have the racing beat setup, I really enjoy it, its quite so your car stays low key but at the same time you gain some good power. The other recommendations are great a good set of gloves are very helpful. The best advice I can give is to start with mounting the header, then from there mount the presilencer on to it. Its more then a pain to mount them together and then line it all up to the studs on the side of the engine.
To be honest even though I love working on my car and you probally do too exhaust is probally the hardest work on a rotary or any vehicle, thats where all the heat is and considering some of the bolts down there havent been touched in 20 years you will have a hell of a time getting some of them off. I almost recommend getting it installed at a muffler shop because they usually can do it fast with the proper impact tools and make sure to get all the mounts right. The hardest thing I found with installing my system was getting all the old rusted mounts hooked back up, well to be honest I didn't I need to take it into my local shop to get done, good luck you will love this system...

14mm swivel-head socket for the rear reactor top nut will save your sanity
And soak all the hardware in PB Blaster for a couple of days prior to the install...
Also a great time to renew all the exhaust suspension components, front to back, as the originals will be pretty tired, especially in a 79!! go to mazdaformance.com/rx7 and download the factory parts manual files, that way you can see what all the suspension bits look like AND have the proper part numbers to order from the maxda parts guy who has probably never even SEEN a 79 RX7!!
enjoy!!

As far as the exhaust goes, congrats. The power increase is quite substantial and the construction is top notch. I don't believe I've heard of anyone losing a RB setup to rust, they're just too freaking thick.

I'm getting there powerpulse muffler, it better be good, or I will be pissed. As it is not cheap. Also folks pointed out having gloves on, but should also have safety glasses on, nothing worse then a bunch of rust and crap fall in your eyes and having to go the doctor to have iron pulled out of the good 'ol shiners and having perminent rust rings in your eyes!

If you don't already have the swivel head socket, you will almost deffinately need one. I got a Craftsman one at Sears. I'd say I spent at least an hour trying to get the reactor off before finally breaking down and buying the new socket. Then the whole thing came off in like 3 minutes. Don't kid yourself thinking you can use a swivel head adapter, you need the swivel socket.

Everybody keeps saying to torque those things up tight, but I'd take it easy during the installation. The studs on the presilencer have been know to twist off if you really monkey-wrench on them and then you're going to be really pissed while you wait another 2+ weeks to get a new presilencer (not to mention that they won't cover you overtorqueing the nuts...).
Just get them tight enough to preserve gas seal and remember that you want to get all the hangers and stuff in place before you tighten them up for good. If you give the suspension of the exhaust a little 'lift' on tightening, it will help to keep it tucked up under the body and keep it from scraping over speedbumps.
I think you'll like the RB system - I'm really happy with the sound and performance of mine.

If it's the SP system, and you have a 79, the only place it mounts to is the motor itself, and the back, where the bumper is...the center section floats free.
you're also gonna need to take off almost all of the heat shields underneath.... they don't clear with the twin presilencers.

Definitely soak the manifold bolts in some P.B. Catalyst every day for a couple of days prior to the install. Also, perhaps more importantly, clean off all of the exposed threads with a wire brush before you try to remove them. Otherwise you might be spending some quality time with an easy out (has anybody ever actually gotten one of those to work?).
I did mine at my buddy's place so I had the use of a full car lift and air tools. The install took about four hours, mostly due to stubborn bolts and such.
Install everything loosely, don't tighten anything up until the entire system is installed. Then make sure everything is straight and go back and tighten everything up. Make sure you lift everything as you tighten things up as LongDuck suggested. It really makes a difference.
Also, be sure to use a good sealant on your blockoff plates. Good luck with it, I'm sure you will be happy with it. Also, as the system gets broken in, the sound will improve and get a bit louder (sounds much better after a few hundred miles)....

I counted 2 rubber hangers on the rear of the muffler, one near the front of the muffler, one in front of the rear axle, and the fixed strap included by RB that goes on the front end of the presilencer section.
Edit: VB lists 5 exhaust hangers for '79-'80, so I've evidently forgotten one. It's possible the SP system didn't have provisions for a 5th hanger. You can use at least 4. You might want to peek under there, and see how many are broken so you can preorder them from VB.
