What Exhaust?

[TS87FC3S]

OK so the exhaust on my new 87 gxl na is rusted off and i wanna do the exhaust right the first time, i want a header back system preferably w/out cats.. what is the best system, price really is not an issue, i want good power, great sound and looks... btw this is the 6 port... also i will be deleting all the emissions and porting/ bigger injectors etc in the future... thanks for the help.

[djmtsu]

You absolutely cannot go wrong with a full Racing Beat set up.

Sounds awesome, looks good, and will last forever. You might also get a little power out of it.

[TitaniumTT]

Agreed, Full Racing Beat is the ONLY way to go..... unless you're like me and build everything yoursel, then it's thick wall for the header and Magnaflows for the cans.

[batmanfc]

I like the look and sound of the obx-r but never had it. Anyone had experiences with it?

[Phoenix7]

RACING BEAT. Any other straight pipe exhaust will be retardedly loud.

[djmtsu]

^^Agreed^^

FerociouP had an RB header with a Corksport catback. It was so loud it made my ears bleed when following on my motorcycle.

And when I say loud, I mean LOUD!! And not a good kind of loud either.

[Rx-7fetish]

Racing beat header, high flow cat, or test pipe, and borla catback. Header is awesome, i have the cat cause they visually inspect it where i live and the borla sounds great, is stainless steel and has a million, yes million mile warranty, like my car will make it to that lol. This combo to me sounds great i get complements on it all the time.

[Phoenix7]

I had the RB header + midpipe and Apex-i dual grapfruit launchers....30 min into a cross country trip and I stopped for ear plugs.

[TS87FC3S]

K thanks guys i was planning on the full RB setup i was just seeing what others said

[TitaniumTT]

Magnaflow > Borla.

I have a Borla on my truck and while it does have a million mile warranty, and so far they say they'll stand behind it, it still rotted out.

Not to mention the fitment of the borla on my FC was horrible. I had to rebend most of the hangers to keep the thing from rattling.

I'm all about the magnaflow for now.

Did you just get an exhaust made with magnaflow mufflers?

[TitaniumTT]

:rofl: That's cute. No, I built the whole thing myself. Magnaflow 3" in and 2x 2.5" outs, and two cans in the rear. All stainless, all V-Bands, quite and the whole thing goes away in less than 5 minutes.

[Nismo]

Here Is my Silver FC with a 2.5" RB downpipe and presilencer, custom 2.5" piping, and a OBX can, the second car is a Red FC with a RB turbo back.

Yes my shocks were blown, and needless to say I am now Rocking a Full 3" RB!

What????:o11: My bolted up perfect, its been on the car since 2005 no problems at all

Dunno, I tried everything before I heated up the hangers to rebend them. Bought new hangers, changed the hangers around, nothing would help. The backpipes were too close to the rear subframe and they would hit. Motor/tranny mounts were fine too.

[Rx-7fetish]

Huh...... sounds like you just got a bum system. Should have contacted them to send you a replacement. Mine was missing the clamp that holds the one side of the y pipe to the other. I called them and they apologized and sent a replacement over night shipping. Now as far as legallity I got an unauthorized exhaust ticket. At the time of purhase it was advertised as 50 state legal. When I went back online to get the page printed to take to court I couldn't find that statement anywhere so I called them about it to get some paper work for court. They gave me some crap about the construction is 50 state legal but the decibel level isn't. Needless to say I was displeased. It got dropped because I stated in court that they don't produce the stock exhaust anymore and when I purchased this exhaust it said 50 state legal and was also the same exhaust pattern and shape of the original and I was trying to keep it all legal.

[TitaniumTT]

Well, when I called them about it, for two things - the fitment and the cheap fucking zinc plated hardware. They said the hardware was fine, I said they better stop advertizing 100% stainless sytem, and they said that my car must have been bent becuase they JIG everything up and blah blah blah. Basically they were pricks.

They are so far standing behind the rotted can on my truck. I haven't recieved my replacement yet so we'll see.

I am going to run the full RacingBeat Road Race Exhaust it just sounds sooo clean.

FWIW today I just built a full Magnaflow exhaust on a Defender 90 Tdi. Only stock part was a downpipe. I wish I had gotten a pic, it was beautiful :D Sounded sweet too..... Magnaflow all the way, hands down... fuck borla, only thing good about them was they kept sending me free hats, that I have since destroyed working in the garage... building Magnaflow exhausts :smilielol5:

[infernosg]

I would say go with RotaryShack's "Max Power" header with a custom 3" exhaust. Without a doubt will provide the best power but will also likely rupture your eardrums and cause massive internal hemorrhaging at the same time. That being said, I will also likely be going with RB's true dual unless I decide to go crazy with this car.

[TS87FC3S]

New question I'm thinking about bridgeporting my 6port.. Will the racingbeat true duals setup still be a good setup for a bridgeported engine?

[Roen]

Another vote for the Racing Beat.

If you are going to streetport or leave your car stock, true duals are the way to go.

Otherwise, I would opt for a Racing Beat Header, Pre-Silencer, Catback combo.

I've owned both on stock engine. I like the sound of the true duals better, it wasn't as deep as the collected setup.

If you want to go really light, customize your setup.

Use a RB header, mated to 2 x RB 1st gen presilencers and customize an exhaust pipe to mate to a RB muffler. You'll save weight, be louder, but still have the distinctive RB sound.

If you bridgeport, do it right. Ditch the stock intake manifold and ECU. Go standalone, and find a custom manifold that matches the new higher powerband of the engine.

[TitaniumTT]

Wasn't I going to build you one of those mani's?

And again, skip the B-port unless you're going to do it properly. Otherwise, just go P-port. Or be a man and add a turbo.... or even two :suspect:

[Max777]

I've got an RB Downpipe, RB Silencer, and an HKS Hi Power....

Honestly, this setup is quite loud, but i think I've got a few exhaust leaks.

It was a LOT quiter when I ran a stock downpipe(with cat) and a main cat delete.

Somehow, I think the HKS exhaust was designed to be used with a stock cat... without one, it doesn't sound as nice, and drones to all hell.

As far as Racing Beat, you really cant go wrong with it.

[infernosg]

Elaborate?

[Roen]

Elaborate?

BP with stock intake mani and/or stock ECU = FAIL, wait no, EPIC FAIL.

Can't really get simpler than that.

[TitaniumTT]

Yeah, pretty much. It's like my definition of half-assing. I would equate it to slapping on a GT35 and leaving the stock exhaust.

Basically altering the port timing and velocity as much as a BP does requires a completely different intake manifold. It also requires much more fiddling with the fuel and ignition curves which you can't do. The potential in the port is there, but not really at a useable RPM without kinda sorta balancing the assembly to see the higher rev's, and at the higher rev's the stock mani can't keep up. How many superjillion yen did Mazda spend designing and tuning the stock intake to work with the stock ports? Ever hear of reversion? Do you think the mani is still doing it's job properly with such radically altered port timing?

Oh yeah, new intake manifold, exhaust, ECU are needed - that's a given.

I guess I was slightly put-off by your expression, the "otherwise, just go P-port". I was under the impression peripheral ports were even more extreme than bridgeports requiring additional work (balancing engine to even greater speeds being one thing).

[Roen]

You should balance if you want to get the full benefits of the BP. Most people half ass it and don't.

Sure it gives you more power, but it shifts the powerband up eleventy-million.

A turbo BP is a slightly different story, it's not as much of a dramatic shift.
