Stewart - Yes, you would need the Long Pipe (111699) and the U-Pipe (111700) to make a complete 308GTB/S exhaust system with the (cat) test pipes and a US version '78-'79 Tubi. Unfortunately, I sold all this extra stuff a long time ago on eBay. I'd recommend that you try the usual suppliers (Superformance.uk, T.Rutlands, etc.) for the pipes (maybe new or used), but you should talk to your Tubi source to see if there's a "Euro" version '78-'79 Tubi (or a '77 308GTB/S Tubi -- since they were/are cat-less) that is more like the ANSA (or Borla) system that bolts directly to the headers -- maybe you could do an "exchange"? (Unless, of course you want to have an exhaust system where the cats could be reinstalled easily -- then stay with the test pipes and US Tubi.) | ||

Stewart, these pipes may be included in the kit (?). I just finished putting my exhaust-system back on my car earlier today. Its a Borla that was installed under the previous ownership. The pipe coming from the forward manifold looks as new as the rest of the muffler, so I'm ASSUMING that it came as a kit  Either that or Tubi will have a muffler for these manifolds you have (could be Euro or Australian versions). | ||

Steve: You know, the top picture is EXACTLY what I have right now. I guess now I know it is an Anza sans cats. By your comments, I agree it is a better system. And being the smart exotic car owner that I am, I am going to pull that off, spend another $2,000 and put on another system. ;-p In any case, it is water over the bridge. I guess to install the Tubi I would need these two pipes then? Any idea where to get them? You still have these you can sell me?  | ||

Stewart -- This issue is similar to the questions about the multiple TR Borla configurations -- both are just a result of different versions of the same model having different exhaust designs. You could have a "homemade� system, but there are also quasi-official 308GTB/S "Euro" (Standard) systems that are really a bit better IMHO than a US system with test pipes. Here's a jpeg of the ANSA 308 GTB/S (non-cat) system with the 4-tip US style:  It's: 1) much less spaghetti (and weight) than a US system with test pipes, and 2) the silencer inlet pipe diameter is large all the way to the silencer whereas the test pipe (and the stock silencer inlet) are the smaller cat outlet diameter of the stock system. For comparison, here�s a shot of a stock �78-�79 US 308GTB/S exhaust showing the pipes/cats/silencer:  | ||

Stewart, I just put a TUBI on my 1979 308 2 weeks ago and there are cats on it. They will be directly connected to the headers on the inlet side and directly connected to the TUBI on their outlet side. My dad's 1978 is the same. If yours is anything else, I would suspect that you are the victim of the dreaded "my uncle Earl owns an exhaust shop down yonder and I'll bet he can make that thare Frerari run like a greased possom" ittis. | ||

Under that sheet metal (aluminum on my car), should be packed with fiberglass (not for muffling purposes, but to insulate for heat). Funny, my GT4 parts catalogue goes up to '79, and they show cats, two of them, for each header (reads: "Versione USA e Giappone"). | ||

There you go Stewart. The problem is already solved for you. Don't feel bad we all make mistakes. They are just covered up in the archives. | ||

That would make sense if these are NOT the cats (and what an idiot I am to think that they are...) because there is no way to remove THESE short of taking out the headers. Referring to the pictures, the flange is attached to the pipe which go straight into the muffler. Must have been a custom job. I guess the cats been removed on my car. | ||

I havea 79 308 GTS and what you are showing are not the cats. They are in line just before the muffler, unless someone has removed them. Also the 79USA 308 does have cats. | ||

Huh?? That's odd. I keep thinking that "pouch" looking thing is the cat. Why no cats on the '79? | ||

I don't think the 79's have cats. | ||

I have a 1979 308GTB Carbed 2V. Just getting ready to put on a set of Tubi and some test pipes from Nick Scianna. I crawled under the car just now and to my surprise I found that my cats are integral with my headers. Only one flange per exhaust. Hooking up the Tubi should not be a problem but how do I replace the cats with the test pipes? That means I cannot just "unbolt" the cats? What's up with that?? Is this an anormaly or that's how the 79 308 are? Also, like the picture shows, there is this sheet metal "sleeve" around the headers, what is that for? What options do I have if I want to nuke the cats and put in the straight pipes?   |
