Default Has anyone actually gotten decent results out of the BEGi downpipe?

All I saw in that trainwreck of a thread were some disappointing dyno graphs and a lot of gum flapping about a comparison between Tony's and BEGi's that might happen 2 years from now.

I don't understand why the hell the wastegate tube re-enters the main pipe at a 90 degree angle, Corky has gone off his rocker and directly contradicted his own advice he preached so heavily in his book.

But has anyone seen any sort of increased spool up from this pipe? It sure didn't look like it from the graphs posted, granted the car was a basket case to begin with, but I'm not about to dump $300 on a downpipe that only works well in theory.

for $85 more for the same material, and based on installing a Tony's pipe myself, there's no chance I'd go with the tony pipe over the begi.

Going with a 90 deg. joint at the wastegate pipe could be because it's a lot easier to weld around that joint (fit the TIG torch in there) if it's 90 deg. I spent a lot of time welding around that joint on my seperated wastegate MSM downpipe and mine came in at a 45 deg angle. I remember thinking, "If this pipe came in at a 90 deg angle like BEGI's, I'd be home an hour ago."

That's all I can think of and I could be wrong. Stephanie could explain more......

I'm not the type to blindly believe "the hype" about anything... but the theory behind separating the gasses for better flow is sound. I don't think I'd call this a 90* angle: http://www.bellengineering.net/Image...2%20copyLG.jpg And, on the Begi website where it talks about the advantages of divorced gas over traditional, spool time isn't one of them. I've got an arts degree, but spool should be directly related to the performace of your wastegate actuator and overall size of the exhaust system, not the divorced gas setup (I could be all wrong here).
I haven't read MB in awhile, but exactly what does Corky contradict?(or post a link to the thread you mentioned).

I haven't seen any back-to-back-to-back-to-back-to-back comparisons on Begi/FM/Tony/Mazdaspeed/custom/DIY/etc. If somebody had the time and got their hands on a sample of every product, and then ran them one right after the other while making no other changes to the setup, then we might have something to determine a cost to performance ratio.

I'm a big Corky/Steph fan. I've said it several times, they're the best small business I've ever dealt with, period. I've never had any company/person of any product category go out of their way to ensure I got what I needed in the way of materials and knowledge.

I'm sure the Begi/FM/Tony/custom products all perform within a percent of three of each other. For my money, even if somebody "proved" the Begi product was in some way made fractionally less power than another product, I'd still have that warm/fuzzy feeling that no matter what happens to it for the entire time I own it, if there's a problem, Corky will fix it. That's worth an extra $50(or whatever) to me any day!

it may be sub-optimal, but the divorced design should still prove more optimal in the end.

btw, sam:

it is fairly 90°, and remember, we are in greddy chat here :gay:

I'll agree that the install was a major pain in the ***. However once I figured out what the problem was it went in easy easy and not rattlles.

I think it's a wash between the two, performance wise no one has proven that the BEGI design is better. Lots of fanboy speculation but no Dyno proof. But I would have paid an additional $85 to not have to **** around with my Tony DP, but now that it's in I have no complaints.

what was tough about the tony pipe install, and why do you think the begi would be easier?

Why don't you shut the **** up. Glum flapping indeed. I was going to ship my DP to Ben for back to back comparisions, but the shipping from Canada to Atlanta was way to expensive. So unless YOU have something to contribute don't be critical of the efforts others have put forth. With out Ben and another member there would be no 2nd option for a greddy downpipe. If I had the power I'd ban your *** right now.

Now **** off you silly ****.

Mine simply did not fit with out modification. I had to cut about 1/2" - 3/4" off the upper part of the pipe to get it to fit with out rattleing. I also had to take about 1/4" off the cat to catback exhaust flange. Nothing a couple minutes with a sawzall didn't fix. Annoyed me that I had to modify it, but for the price I'll live with it. Now that it is in, I have zero complaints. And if I have to install another one I would know what needed to be done before I installed it.

Interesting. I can't comment as not only did I get mine used, but I also replaced the cat with a test pipe and replaced a section of pipe between the test pipe and muffler at the same time.

I also replaced the cat with a test pipe. Other than the two issues everything fit well. Could be my car is a little tweaked, motor mounts? Either way it's in and no longer rattles.

Yeah, I've got something to contribute. It's the novel idea of posting about your shipping troubles rather than keeping mum and having people wonder what the hell is going on. Gee, maybe a few members would even have chipped in to help cover shipping costs if you would have put people in the know. Probably not much chance of that happening anymore now that you've revealed your ****-poor attitude towards the project.

There's a good reason you don't have the power to ban people and I think we all just found out why.

If you're so "Mr. I've got something to contribute" gung-ho, then YOU DO IT.

Jay volunteered the use of his Tony pipe to me. I didn't accept it. The freight and customs fee would have been $200 or so. If Jay & I lived closer, it would have been viable, and it would have been done.

The only **** poor attitude is on your end. At least Jay tries to be helpful.

You know we've had 2 different "cheeses" here. And they are both douche nozzles.

Do you think that members of the forum would have chipped in nearly $200usd to ship it from me to Ben and then back again? In the end shipping it was not realistic, and with having to cross the boarder 2X the chance of a hassle was high, and would have taken a lot of time.

My mistake was to offer before really thinking through the logistics and cost. My bad, my enthusiasm got a head of me. **** poor attitude indeed.

I feel like putting you in a corner, you whine more than my 2 1/2 year old. I suspect your days are numbered anyway.

Giving up too easily is indeed a **** poor attitude.

A 20 lb package is $27.90 each way for me with my UPS account.

BUT HEY I'M JUST A WORTHLESS POSTER WITH NOTHING TO CONTRIBUTE. MOVE ALONG, NOTHING TO READ HERE

Hey, lets try to pull this thread out of the ******* with a real response!

The contradiction I'm referring to is on page 145. The diagram lists right angles as "poor" and the paragraph at the bottom reads, "Exhaust gas return from the wastegate to the tailpipe after the turbine should receive the same forethought as gas entering the wastegate. The principle here is to avoid interfering with exhaust gas flow exiting the turbine."

I don't doubt the fact that BEGi is a great business. I've sent a few emails to them and Stephanie has been very helpful and their reputation on here is stellar. I'm not saying BEGi sucks because the downpipe design is less than ideal, I'm raising questions and hopefully getting either an answer (as to why the pipe enters at a suboptimal angle) or a result (a revised design). This is the benefit of dealing with a small business, discussion can bring about change and better parts for all of us. This is in stark contrast to a large corporation, how long have we been saying the GReddy manifold sucks? They don't care. Bell does.

The point raised about the angled piece being difficult to weld is a valid one, perhaps that really is the reason why it isn't integrated better. I know BEGi takes pride in the appearance of their pieces and the shallow entry might require an ugly weld. I'm a function over form guy, though, so I'd take an unfinished pipe and make the ugly weld myself if that's what it took

I believe that you should call BEGI during business hours tomorrow and ask to talk with Corky. He would be willing to explain anything you need explained, and will probably start talking about other **** to. He is a nice guy on the phone and will take time out of the day to talk with anyone.
