G-Down has sent an exhaust system to Raby Enterprises for testing. The system sent is an 15/8 "Shorty" with crossover tube and megaphone tips with ceramic coating. Stay tuned for the results.

We'll see how it performs. I have six TI engines coming up to finish next month varying between 1915 and 2332cc in varying stages of tune.
Not looking for simply net output, more at efficiency and how the introduction of the exhaust impacts the tuning of the engine. I'll not be posting results online, I will provide the results back to the supplier to disperse as they see fit- Just like what I do for companies that pay for my services.
Anything else just creates a pissing match.

looking forward to hearing the results..
I like the look of the "Forward Exiting Exhaust" as it is DIFFERENT,.....unlike your average 'merged header' that EVERYONE else has
might sound real bitchen with a couple very short "Cherry Bombs" on it.......

The system arrived today. I measured it and it will not fit onto my primary engine dyno and the R&D dyno is set up for watercooled Porsche engines permanently now.
So I''ll have to do all the test work on my chassis dyno.

Caveman... I need to borrow your car to test this system on the chassis dyno. Your car is perfect since we have baselines and its a very popular combination. Game??? Caveman, Wait till you see what the Tech day is like this year... I added another building and have really been busting ass on my property to make this place even better than before.. |

I now have a 2110 in my car. But the engine and trans out of my car has been transplanted into my nephews car. Im sure that he would be moe than willing to let you use his car to play with. Just let me know when you need it.
But if you would like a 2210 to beat on I got the one you need. There is no base line for that one yet. Sounds like a fun time at Tech day, so Ill see you there if not before.

we are going to host a car show and Dyno Day here later in the year after I finish all my changes to the property. This particular tech day is for our local VW club only prior to our Poker Run... Cave man, that will work.. I am ready when you are, any time other than the week of the 13th, I have a class to host that week. |

I tested the exhaust this weekend during a "Tech Day" we host annually for our local VW Club. The test engine was a 2110 that made 122 RWHP consistently.
Claudio, contact me for the data and to arrange shipping of the system back to you.

When I ship the system back to Claudio I will provide all the data to him from the dyno runs along with a commentary on the effects the system had on the test engine when compared to the conventional 4-1 system it was tested against. He can post the results or share them with who ever he would like after that.

Claudio just had the system shipped back last week, so he hasn't received the results yet.
More than 20 local VW enthusiast were present to see the evaluation, back to back and some even helped install the system... They saw the numbers and the reactions that the engine had with the different systems...

Its not a case of anything other than the fact that I don't have time for disputes... Any information at all is basis for confrontation.
No matter the results, some jackass would run his mouth.

Wow, a little harsh dont you think? This guy built a product shipped it to someone for testing and now has his results back. Even if they werent the results he was looking for it sounds like this is the type of person that will make refinements and try again. At least he's willing to put in the development to make sure he has a product that he can feel good about selling. Lets give the guy a little break. I'm sure this isnt the last time your gonna here about his product. I'm sure Al's headers are great Eddie but I dont think I'd jump on here and say his product must not be that good if he wasnt willing to share his testing info on a new prototype with everyone on this forum. Just my $.02 Gavin |

If I am correct the initiator of this thread proudly announced the testing and asked us to stay tuned for the results. G-Down has sent an exhaust system to Raby Enterprises for testing. The system sent is an 15/8 "Shorty" with crossover tube and megaphone tips with ceramic coating. Stay tuned for the results.
Rumors, Assumptions, Speculation, Hearsay (RASH)…this is what happens when facts are not made know to those concerned. I too, have marked this thread to await the results. Now I have a rash breaking out in my mind, because I do not have the facts and can only assume that the outcome somehow fell short of anticipated results. If it were as good or better than expected, we would have heard something shortly after this was posted: Claudio just had the system shipped back last week, so he hasn't received the results yet.
More than 20 local VW enthusiast were present to see the evaluation, back to back and some even helped install the system... They saw the numbers and the reactions that the engine had with the different systems...
RASH is the symptom, lack of information is the problem. Telling the whole story and getting the facts out will solve the problem. |

And obviously he's not ready to release results. He may very well have more changes and testing to make before we here about the results, like any sensible manufacturer would do.

My thoughts exactly...never rely on one set of test data. Substantial road testing would be nice as well... |

I just finished an abbreviated report for Claudio. The report covers manufacturing overviews, fit, finish, efficiency and net output as well as tuning observations. Of course we did not put a ton of time into this, just one single day and tested the system Vs. one well known 4-1 arrangement. Luckily that one comparison spelled out the differences very clearly. Had this been something I was evaluating for a "paycheck" the time we put into it and the data acquisition would have been much greater. I even wanted to bring our scales in and weight the car before and after on all 4 cars to see just how much the G down system shifted the weight forward, since thats one of the claims of the system.
The system that was tested DID incorporate an "H pipe".

Well, my .02 cents would be to pair 1 and 3 and 2 and 4, instead of 3 and 4 and 1 and 2.
Also, I would make the primaries longer, and equal. then y both together....dang, I just built a 4-2-1 header...
