I have a 87 n/a with webber dcoe? 48 carb,racing beat intake and racing beat road race header( dual at the end doesnt come to 1). I need to get the rest of the exhaust but want to stay on a cheap budget. I have no worries about emissons because I will be going up state later on and they dont do emissions in upstate ny. Can I get the RB streetable header/collector (2 to 1) then get the cork sport powerseries cat-back exhaust system connected w/o it being extremely loud and all hooked up even to the right length? Or do I need other stuff? I dont know all that much about exhaust system but im trying to learn on it. Can anyone help me out?

in your situation there are a few things I might do, I don't know exactly what budget you're looking at, but if you don't want loud you want the RB or Borla cat-back, if you just don't want extremely loud, you need either a cat or a good pre-silencer (RB for example) and you may want to look into a Borla XR1 to put in the system wherever you can fit it best (maybe the beginning of the cat-back). It's a good muffler that won't restrict flow (I believe I read they flowtest better than a same-size straightpipe). I would go with the RB 2-1 header (or collect yours) to the larger RB turbo pre-silencer (if you ask me the NA ones are too small for its noise), to a borla XR1 ($100 or less), to (or in) the corksport catback.

sorry for formatting... I'm drunk.

I honestly think you should do it right, buy the presilencers and have a cat-back made or get the truel duals.

I did the collected header/presilencer + CS cat-back, gains we nice, I lost alot of weight. But now its VERY loud. And if you don't want loud I wouldn't suggest this to you.

Just about anything you put on the roadrace header will be loud. The other problem is that very few people make exhausts that bolt up to it. To my knowledge, the only ones are racing beat (duh) and corksport. There might be a borla muffler, but I kinda doubt it.
Edit: I'm a dumbass and didnt read you post well. Yeah, you can get the header and whatever, but you MUST have a presilencer or cat. It will be basically undrivalbe on the street otherwise. I suggest you just bit the bullet and get the RB presilencer. It is very high quality and wont warp like some other companies products. After that, you can get pretty much any catback made for the FC. Just remember that if you get a cheapo e-bay nock-off it'll probably sound like crap (or rice)

I looked into the racing beat presilencer and it only hooks up to a singal header. Mine is dual and doesnt go to 1 like my dad has on his rx-7 (same as mine). If someone can fine one that will hook up to my head that would be great, then I get get the rest of the exhaust that I want (the cork sport series system).

Is there any pre silencers that are dual to hook up to my header right and then comes to a singal so I can get the exhuast system I want.

If your not too worried about being loud you can go with the setup I am running. I have a Racing Beat collected header into a pre-silencer into the 80mm/stock cat Corksport exhaust. I will say, its loud...really loud but its got a sick fat tone to it and with the fat lope my carb'd motor puts out its awesome. Get the silencer tho, it helps more than you would think, but increases the tone to a slightly higher pitched one. I love my exhaust, and I can still hear the radio! But the real radio is driving w/out the silencer and actually FEELING the rotor pulses in your chest

Word,

The Presilencer in the muffler is essential for a long road trip.

Jager, you pretty much have what I want to do but do I need a pre silencer to make my exhaust the right length so the end of my exhaust will meet up good at the end of my car? I wanted to get the R.B collected header then the cork sport power series silencer insert then the cork sport power series exhaust system. Can I just do that and it should be fine or will all that not add up to be long enough to come out the end?

no one?

To run a normal cat-back with the RB collected header you NEED the pre-silencer. RB makes their headers shorter and with the pre-silencer it ends right where the stock cat would, thus allowing a cat-back to fit right in. Hope that helps

So all i need is the presilencer to and it all would hook up right?

I'd go with the RB road-race presilencer. You'd still be maintaining true duals (2 pipes inside the silencer), and it bolts up to the factory y-pipe, or the racing beat y-pipe.

Ok i saw and heard a clip of a FC on this forums that was a little bit loud but barable and it was the setup I was going to run. I searched for the thead and I cant find it. It is a true duel set up with pre silencers.

RB header with collector cut off, running into 2 glass packs being used as presilencers, into pipes running to the back exiting the stock location though N1 style mufflers. It wasnt loud at crusing speeds but sounded sweet under hard accleration, and sports driving. I wish I could have found that clip of it maybe the mods can help on this.

If you're using the road race header you need the ROAD RACE Y-PIPE.


The normal Y pipe WILL NOT bolt up.


My advice is to buy the FULL road race setup from RB.

Yup ! RB Collected header goes into the presilencer (make sure you get the NA one for coupes, otherwise you'll have to find another way to actuate your ports), then whichever cat-back of your choice. And the CS presilencer goes right into the muffler, there is a little bolt that comes with it. You tighten it and walla!

Thanks jager thats that i will do then.

Yeah, there is a RB presilencer that bolts up to the road-race header, but it has two outlets also and requires a special y-pipe. http://www.racingbeat.com/FCExhaust/RR%20Exhaust.htm
Theres the link. I think i heard someone say there was a corksport catback that connected up somewhere to the RB true dual system, but Im not sure where. It might have been on mazdatrix.
Basically the only way to use any catback you want is to get the RB streetable header(one outlet) and go from there. If you do go that route, i strongly suggest getting the RB presilencer as well.
