Rb Header to Straight Pipe to Muffler?
I ordered a header off of racing beat and am about to order a straight through highflow muffler. Can I just get a straight pipe welded between these two? Want diameter piping should I get?

It is not as bad as every one makes it out to be. But this is from a guy that rides 2 strokes. I had a rb header with a bonz blown out cat(pretty much straight through) and it was more annoying than loud. Granted that this was also on the stock muffler. It made a really twangy sound. Butup around 6k on the dyno people said that it sounded pretty good. I felt like a ricer on the street though
You shouldn't have this problem if you get an aftermarket muffler though. If you take it some place you might wanto to see if they will test a couple different ones on your setup.
As for piping I have 2.5" all the way back but I also have a SE.

Did you have a stock muffler?

Everyone’s definition of loud is a bit different. I have a RB Race Header & Street port center section to a 6” round Dynomax Ultra flow muffler 3” in/out and it’s too loud for me……and my neighbors come to think about it. :-) But this isn’t a street car so I can live with it. Regardless if you think it’s loud or not, it will certainly be too loud for the local law enforcement officers. So unless you have an inside connection with the law, I wouldn’t run that setup.

Everyone whines and complaines about not wanting their RX-7 to sound like the Honda boys. All they want is to sound like us!!! They aspire to have true sport cars with true sport car sounds!! I say go for it! I'm going RB header, true duals back to an aftermarket muffler.

it will get louder as you break that muffler in and that rotary beats the **** outtah it with flames and heat. i have a RB header with 2.75 pipe all the way to a stainless steal muffler and after about 500 miles on it, its LOUD, very loud. But i shoot flames all day long

I have straight pipe from stock header back to a huge magnaflow (#12640 6" diameter, 27" body, 33" overall length, 2.5" in/out). At $80 and a lifetime warranty the price is right. It starts right at the rear axle and points very slightly downwards. I have not had problems with ground clearance because it hardly hangs any lower than the stock muffler, and because it is so long it gives it a very nice tone (people from the NW section that have seen and heard it tell me it sounds good and ask what muffler I am using). If I were to do it again though I would go with a 5"x8" oval muffler for a better fit, say a magnaflow #12368 24" body, 30" overall, 2.5" in and 2.5" dual tips out.

are you guys insane?!?!?!?! I have the RB streetport header, to a 2 1/4" dual primary to a 3" straight pipe to the RB powerpulse muffler.
Not all that loud at all!!! Still better than half as load as all the hondas around! It only gets loud when I get on it and rev it out.
The only down side is that it is a little tinney. And I think thats because of the 3" section.

So I've had my exhaust for a long time and its loud. I used to love it but I went stock to pass smog (except i didnt pass) and I like the quieter Rx7 a little more.
I was thinking of adding another one of the Magnaflow 2.5 inch/out 4 round mufflers to my exhaust to quiet it down a bit. Also I'm planning on getting flanges installed because my exhaust is one piece from the header back. Which means I have to drop my rearend whenever I change my exhaust.
Does anyone have any opinons on the magnaflow or know of anything that would be better. Also what flanges should I get? I'd like to get ones that have easy to find gaskets.

I have one of these.
I blew some compressed air through it and a whole bunch of others. It faired well. But yes like Wacky said, get an RB 2.5" universal muffler. It was by far the most muffled of the ten or so mufflers I tested this way. Impressively quiet. Of course it depends on how you feed it. Dual long primaries will be loud any way you slice it.
