RB headers vs. Pacesetter Headers vs. Do it yourself

[SleeperSeven]

YEY! I get the first exhaust topic!
So lets start it out with headers.
I would like to know what everyone thinks about the different types out there.
And what are the pros and cons of each type.
And I personally like to fabricate (everything) so.... howabout homeade ones too!

The first thing I have to add that was a learning experience was... headerwrap = headerbomb, then the suped-up lawnmower sounds follow.

As I understand it, Pacesetter headers aren't cut very well inside the joint, leaving a small edge, or obstruction. In other words, rumour has it that they are manufactured rather sloppily. I also thought they were thinner than the Racing beat. Never having had one in my hand, I can't say from experience.

[SleeperSeven]

Well, if luck were to have it.... a body hammer and some minor skills fix the crude fab work on the Pacesetters... and for thin.... well....... I dont recommend heat-wrapping them as the rear runner and the first elbow tends to blow a hole big enough to shove a golfball in...... ask me how I know............. but.... they patch up nicely with a mig and some scraps of old exhaust layin around

i would say RB is the best unless you actually know what your doing designing a header, or can afford a more pricey alternative.

[Sterling]

I have to agree. They are built to last.

[SleeperSeven]

I'll agree with that, though I havent had the urge to spend that much on a header yet.

also..... has anyone heard of an old company that used to make 12a headers..... rotary engineering i believe it is?
I saw one on ebay awhile back and thought i lost my mind.

Talk to Kentetsu about that.

Talk to Kentetsu about that.

Huh?  If I am supposed to be knowledgeable in this subject, then I'm afraid that I have been slacking in my duties...

However, I do happen to know that RE headers are very sought after and regarded as one of the best options even though they are no longer made.  You should have grabbed that one you saw.

Of course, since I'm not an expert on this subject, any of the above information may be total crap...

I have a full RB SP system. Although once the engine gets it's BP I will most likely be going with the RotaryShack header (I think they mentioned a 12A version was available) or a one off version. The BP will need a lot more flow than the RB exhaust can give. The Rb will however survive a nuclear holocaust, even if the rest of the car won't. I have no experience with any other exhaust.

I wish I knew where I got it, but I've got a stainless front section, custom mild steel (thick wall) center section and my own collector right before the axle.
The stainless front has lasted much longer than any mild steel header I've had. I've also got it wrapped with a header wrap called "inferno" and I have not had a single problem with either the wrap nor the header. Be careful just jumping to stainless, because it does seem to reject more heat than the thick wall mild steel header (racing beat)  I initially used.

I've got this system on an ITA car, with a flowthrough dynomax muffler. I made 125hp at the wheels in IT trim (no porting, jetted carb). Note - it is loud, about 90 dB @ 50 feet.

Nice job, rotayt.

Kentetsu, I thought you were trying to get a one time limited production of RE headers made again, or some such...

[lascelles]

It was Mind Train.

What about Rotaryshack

[orion84gsl]

Rotary Shack makes a nice header, but they are about $700US. That's almost the cost of a full RB system. If your only looking for power, then that's the place to go, but most of us drive our cars on the street and run enough risk of being pulled over.

[Kentetsu]

I've heard rumors of a Repeed exhaust system in testing...

But yeah, Mindtrain would be the way to go, if only they were still available.  Get 50 orders together for any part of that system, and they've said they'll fire up production...
