I i'm going to buy some headers for my car. Just woundering if you just bolt it on or if you have to do something to put them on. someone was saying something about the 5th and 6th ports or something. does anyone know anything about what need to be done to put the headers on, thank

you have to remove the 5thand 6th port actuators, and then you should be able to remove the 4 bolt holding the manifold on

rx78788

do you just remove them to get the bolts to the manifold off. and then put them back on. or do you leave the actuators off.

You can still have the aux port actuators with headers. Otherwise it would defeat the whole purpose of the header.

yeah yous just have to remove them to get to the bolts, if you can wait till some time in april i'll do a write up when my RB header an presilencer go on, i'll take pics too

rx78788

as for the fit of the headers. will it bold up to the rest of my stock exhaust system. or will their be welding invloved

do you want to remove your cats?

If you get the RB headers, you have to get the presilencer for it to bolt up, since its longer than the stock manifold. If you do that, it bolts up to the y-pipe. If you want to retain the cats, you will most likely have to make a pipe to get it to fit properly.

while i'm getting some pacesetter headers. should i not get them then. because i only have money for the headers at the moment. Should i just wait untill i havethe money for both

i personally would wait, i have head that pace setter arin't the best, but it's what you want to spend right.

i got a deal on mine header, presilencer, and TII exhaust for $300 having friends with the same car is kick ***

You could always get the RB downpipe/presilencer combo for $300. According to Racing Beat, that gets similar power gains on cars with stock or lightly modded induction. Also, the pacesetter headers might not need an extra attatchment to work. I don't know anything about them, so Im not sure. Another thing to look for is whether it reliably opens the aux ports. A lot of aftermarket setups dont allow them to operate with an open exhaust.

rx78788

yeh i don't think that i'm going to get it right now. so how much hp gains are seen from the racing beat headers and the presilencer combo.

And i'm still confused about this whole 5th and 6th port thing, can someone tell me more about what you guys keep saying about that what makes them open

When i first bought this car, the guy had the cats howled out. and the air pump was not on. And it was not running right so i had another engine for it, and swap it. when i went to find the problem i fond that the 5th and 6th ports were all carboned up. is that the result of not putting the exhuast in propoly. this whole 5th and 6th ports thing is just comfusing me, why does it carbon up like that..

does anyone have pics of the 5th 6th ports? i am more lost than this guy, cuz he knows where the actuators are. i sound retarded huh. well its cuz i am. give me a vw 1700 and i will make it purr, show me a rotary and i will scratch a hole through my skull.

the actuators for the 5th and 6th are right bellowthe lower intake and right above the manifold.

here....go here and look at his exhaust this webpage has been posted before. But it shows you where the ACV is blocked off and how your ports will still open.....take a look.

I've been using my MindTrain header and Bonez cat for a few months now and it's AWESOME! I really can't recommend this setup enough. The 1/8" header tubes cut most of the ringing you usually get with headers and I think the Bonez cat is probably more effective that a presilencer for cutting the "Chainsaw" bark out of the exhaust note. My power is greatly increased, my noise levels are reasonable and my nose says that my emissions should be within legal levels.

You dont really have to have a presilencer if you do a mid pipe... Only problem with that is you would have to buy the flanges and 3" piping and get it welded at a local shop or something... Great for a straight flow through if you looking for power. But its all up to you.

I put the RB Header and pre-silencer on my sons 89NA about 2 months ago and didn't remove the aux. ports to put the header on. I just took the factory exhaust manifold off( cats long gone), unbolted the remainder of the exhaust and put the header and pre-silencer on per the instructions. I thought it was a pretty simple job and the fit was perfect. Why would you have to take the aux. ports out to install the header ?

How loud is it? And what are you using for cat-backs? Single, dual, strait-though muffler, stock? I've got the DP/presilencer from racing beat, and I love it, but I think Im gonna get the header once I get enough money and get all the other stuff I need. Just wondering if its rediculously loud.

I havent had my 5th/6th port acutators in awhile, but Im pretty sure you dont need to remove them to unbolt the exhaust manifold. Also the Pacesetter will bolt right up to the stock exhaust, but the first cat needs to be removed.

racing beat says 22 hp out of all header all the way back with presilencer y pipes and mufflers. i got 19 hp when i put it on a dyno and was stoked
