Default TJWong's custom 'X'-pipe from Dr. Gas.

New thread spun off from thoughts here:
Adding LT Headers and relocating CATs BEWARE

contact me again and I can fax it to him The cost is about $200 and
shipping.
Does this include the leading and trailing pipes welded to the 'X' or
do those need to be added by the purchaser?

Automatic friendly? Diameter?

I'd be interested in participating if Dr G. felt like making a run.

Forum rules allow for the posting of a factual account of an unresolved dispute so long as every reasonable effort first has been made to resolved the issue offline. After the factual account has been posted, it goes into the archives and cannot be reintroduced on subsequent days and in a variety of sections. The dispute in some of the links you provided is in conflict with those rules/guidelines.

Bottom line: Nobody is exempt from Forum rules/guidelines. The vendors mentioned must stop using the Forum to promote their goods/services or risk being banned. The loyal followers of each vendor much stop promoting the services provided by their friends because it has exceeded what is allowable. The bashing of vendors (supporting or non-supporting) and Forum members is always inappropriate and must stop.
I not not trying to create trouble for myself, tjwong or anyone else. If
that is where this thread is likely to lead, then let's just stop before
we get started.

There is nothing wrong with this post IMHO no URL, address, phone number or e-mail so I cant see any problems whats so ever. I think this is a subject many would be interested in, a direct bolt in X pipe would definatly be somthing on my list of things to do.

Oh, I agree absolutely. 'IF' there is a problem here, it is of my making.

I didn't add the reminder about forum rules to direct it at him, it is
for me and for anyone choosing to post here.

That is the most functional / cleanest C-4 exhaust system, I have ever seen. One in which I will copy, in the near future....

Very true I have contacted him in the past and he had mentioned neerding the car for this type of set-up.
I agree w/slalom4me it is one of the best I have seen also, mine is very similar (RT ) except tabs need to be welded to the pipes for the LT brackets that I have (which it was TJ who helped me w/that info!) It was his set-up and -=jeff=- that I wanted to copy.
Wlhen I get out of work I will try to get a couple of shots, problem is they won't be as clear since the car is not that high in the air.

The X pipe comes just as you see it. I designed this X to replace a resonator from a B&B kit. So demension wise it is the same size as a B&B resonator. It is about 27" long. The tubes are all 3" OD and it is made from aluminized 16ga steel. I had it ceramic coated to keep the corrosion down here in the Oregon area.

Tim, I'm pretty sure those are the B&B mufflers TJ is using. I have the whole B&B system on mine with thier xpipe.

Is the front hanger on the LT1s only used on the M6 or on
the A4, too?

I picked up rear hangers some time ago and recall that neither I
nor my friendly GM parts person were able to determine if there
is a front hanger. I can see one clearly on tjwong's M6 car.

Here's a question...

Does the stock resonator combine the flow from both exhaust banks? If so, then it leads to other questions about exhaust crossover placement.

I didn't "search" before posting so feel free to "red-head stepchild" me

I have the exact same setup on mine as TJ's. Back before the Forum rules I started a Dr Gas Group Purchase on that X-Pipe, and got about 10 people to go in on it. I believe it was $169 at the time and we got it for $139. Have no idea what it costs now.

TJ's setup looks awesome!

Thanks, I'll scout for the p/n next week. If I draw a blank, I'll PM or
email for help.

My system was originally a B&B system which fits all 92 and up LTx C4 cars. And most earlier cars with the replacement LTx exhaust hangers. I have installed the B&B system in "thetoy's" 89 M6 car using cutouts over a year ago. All you need are the LTx hangers for either the A4 or the M6 trans. The rear hangers are the same for either tranny setup, and you will also need the rear muffer hangers that are just L brackets bolted to the mufflers.

I'll re-voice my question...

Does the stock resonator provide a cross-exhaust bank function?

If it combines both banks then we're back to the "X" placement. And what does the placement provide? Apparently on the GS it must've done something. GM "X'd" it right before the resonator.

Fad or not?
