Holy crap that is art work. They look like my Ti headers on my MV Agusta. Can they make them out of any type of material?
Hey Flyguy, The 348 guys have the stooges.... What would one name this gaggle of buck toothed critters? Which one is Bruce?
Im not sure Dave Maybe we could consult with the dogs owner...He has opened a shop welding and fabricating 355 headers at a really cheap price. Image Unavailable, Please Login
Jetfixr........... you posted that in the entirely wrong thread--go to "Picture of yourself thread" in Silver subscribed.
Hey, wait just a dog-gone minute here........... If the truth be known, this is really a pic of what Dave was seen leaving with after one of those bawdy SCCA Luau's back in the 70's. Dave I hate to break the bad news, but after all these years of your questioning why the SCCA banned Luau's????????????...Well, let's just say it was because of a "Horny Night at Sears Point" ,the fact that there was no moon out and someone forgot to warn you about the side effects of drinking 2 case's of Pabst Blue Ribbon. Does Kris know about this???....I won't tell...lol
Would Tubi headers and Fabspeed high performance cats take care of the midrage lose on the 5.2 cars? Not sure if both can be used together. Can you wrap the original heatsheilds over the Tubi headers? Last what real power gains would this combination yeild? $6681.34 http://www.vividracing.com/catalog/exhaust-parts-headers-c-4246_4249.html?class_9=931&my_type_id=8&class_8=927 $1995 http://www.fabspeed.com/ferrari_355.html Thanks
I think Tubi dropped the production of these manifold already as I was told today! BTW, anyone dynoed their Fabspeed headers YET!!!
Where did you hear that from? I had my Tubi headers installed earlier this year and am I am quite pleased with them. That is not good news if really true...
I called Tubi this morning to get some pricing, and was told they have been dropped for future production. There may be a few sets other vendors have in stock still, but I doubt it since they are not cheap to be stock item.
That exhaust manifold flange to primary tube weld is just awesome. That set-up is like art. Do any of you guys tig weld? I love those small petit welds but personally end up always adding more filler. When I do those small pretty welds and test them on a bench vise with a huge pair of pliers I can break the joint at its weakest point which would be the tube weld interface. When I add more filler the joint is always more durable, i.e. make the joint look like an ugly mig joint. Anyone else have that problem? I am a self taught welder and only use the small pretty welds on things that don't take much force like an oil tank. Maybe I am doing something wrong...comments?
Smaller welds with less filler are indeed weaker. But usually when one has a 100% circumferential weld x4, tubes it is pretty durable in a variety of applications. Small welds like that are similar in strength to the parent material and if any preloading, vibration/harmonics are addressed (in this case the collectors will help dampen vibes) it should last a while .
Heck, when I was young and had a steady hand and could still see well...... I still never ended up with a TIG bead that nice.
Sometimes I'm not so sure that waking-up is a good thing. Dave, what ya think about all this header stuff??? I have no problem with better tubing.....no problem with 4-2-1(nice trade off for increased low end torque)....no problem with text book tig welds. But there are a few things that I would look at: 1. As always, the heat shielding thingy.....at the bare minimum coated headers(the black stuff...no white or chrome looking crap-if you don't know why don't ask me) and shielding alt,a/c comp. and everything else in sight. 2. Longer primary tubes.....if you keep the rest of the stock exh. this will require shorter cat's. 3. The construction/design(me really likes Burns) of the 2 and 1 collectors. From the pic's posted by David they look to be Burns or equal. 4. IF YOU KEEP the secondary exhaust I would like to see enough length before it Y's off, so the pre-cat O2 sensor bung can be placed right at the beginning of the 1 collector. This just might help in resolving some of the problems I see with Ferrari's by-pass exh. system...no gurantee's though until I do some testing. As for price????? Well, if it were done to "MY SPEC'S and DESIGN REQUIREMENTS", then it would not be unrealistic in this day and age...especially for an F car. May be able to save cost by re-using the Ferrari header flanges, and as for me I DO NOT WANT AIR RAILS....lol BUT!!!!!!! If it is just to go back to everything in stock configuration why wouldn't QV's repair which reuses the stock heat shielding not be sufficient....and costs much less. I have no experience with QV's redo so I can't say for sure if it provides longevity at a bargain price.
I gave up on this header stuff a year and a half ago. The cost to build what I drew up and want assures its failure before the first one is built. There is power, reliabilty, longevity and torque to be gained here but the cost to obtain it is too great for anything but a one off effort. Maybe David can put it together, I sure hope so.
Seems like there is a market here for aftermarket headers that actually hold up. I never really did any research on the 348 or 355 becaue I wanted the 360. Does someone make an aftermarket header that holds up?
There is a market for aftermarket headers that last, work as good as OEM or better and have no other baggage that are cheap. Cant be done on a production level as R&D and quality costs money.
Lusso (David), Ventura County is a small place, so I believe the company you are considering for this project is based in Camarillo, correct? Their name starts with an "R" and ends with an "er." I will refrain from posting their name because Jim and Brook would not appreciate getting a bunch of phone calls for a product that doesn't exist yet. With that said, I can vouch for the quality of this manufacturer. In a previous life, I used them to make intercooler pipes for VW and Audi 1.8T engines. Their quality was outstanding. Ask Brook if she will weld the 355 headers personally. Her welds are as good, or better, than robotic welds I've seen on other mass-market exhaust systems. Jim trained her well! Good luck on your project!
There is no question in my mind that David found a very high quality builder, the photo's speak volumes for those that know what to look for. I am sure Dave has a ton of time involved in this to date and there isn't even a set of tubes welded up yet. Finding someone that produces quality work from the start to the finish on each part every time is no easy task, let alone finding someone to design these that understands all of the factors in play. Let's respect his investment in time and effort and allow him to follow this through to conclusion without mudding the waters. This is his project and if he can get it put together he will have earned his money the hard way. The question I have is are folks willing to pay for the quality it takes to have a final solution to the problem? There are far more things going on here than first meets the eye. Many dynamics are involved with the headers, the engine and how they breath, that few understand. Knowing David I am sure he has a firm grasp on this. Are folks willing to pay for this? I am if he can get this put together, Made in USA has a whole new meaning to me these days! I am no longer price shopping Ferrari parts, I am shopping for quality as I am fed up paying the price for sub standard quality, enough is enough! Stick with it David, it isn't going to be easy as I am sure you have already found out.
