Hi guys I'm considering a Capristo exhaust for my car as it goes back on the road. Problem is that being a UK delivered car it has no cats or pre cats, and the end of the headers runs straight into the muffler. Seems that the Capristo system is designed for Cats like the picture below. Has anybody seen a way to adapt this system to the standard exhaust flanges straight off the manifolds? You Americans speak of test pipes and pre cats, but what exactly are you talking about? Image Unavailable, Please Login
Here's pictures of my exhaust manifolds and current exhaust system. I need to make the Capristo pictured above, fit to my car as seen below. Image Unavailable, Please Login Image Unavailable, Please Login Image Unavailable, Please Login
The precats are items 23 and 24, and the cats are items 18. "Test pipes" are available that replace either the precat or cat (i.e., in both cases it's just a pipe assembly of similar length/shape): Image Unavailable, Please Login The bigger problem that you'll have is that your euro headers are physically longer than the US headers. Consequently, you'd need to buy a set of US headers (in addition to a set of precat test pipes and cat test pipes -- or F actually makes test pipes that replace both the precat and the cat at the same time -- see the full Table 20 in the late TR SPC) to just have everything bolt together -- assuming that the structure(s) that hangs the muffler and all the tailpipe locations are the same (I'm not sure about that -- note that there's a lot of extra mounting hardware for the US muffler on Table 20 that isn't shown for the euro version on Table 19 -- so you'll need that stuff, or some sort of substitute, too, even if the chassis hard mounting points are the same). Probably the most direct, and lowest cost, way would be for you to have a muffler shop custom fabricte some Y-pipes to connect your existing euro header outlets to the Capristo muffler inlets (assuming that you can mount the US Capristo muffler to your euro chassis with the extra hardware).
Thanks Steve. Yes, a set of locally produced connectors looks like the way to go. Would you have any images in your 'reference library' of the correct way to hang a USA / Euro style exhaust?
No, I don't (but I'll take a pic, or two, this AM after my camera battery charges). The center, square flange on item 10 (the spring thingy) in that Table 20 SPC figure is what actually gets bolted to the chassis.
I hope you can get that Capristo on yours, it was the best sound I ever heard coming from a TR when I put it on my Miami Vice car. It was the level 3.
Sounds like you need something like the pic below. One left and one right. Only thing this company makes them with a cat in the pipe, maybe you could contact them and get a pair with no cat.

Robert, need these ? http://www.ebay.com/itm/Ferrari-Testarossa-512-TR-Catless-Pipe-Test-Pipes-Resonated-De-Cat-Pipes-/370645673994?pt=Race_Car_Parts&hash=item564c34280a&vxp=mtr Mail me .....
So much difference Steve. Those brackets don't even exist. The frame rails are different and the exhaust is mounted totally differently. I'll manage though. Where there is a will there's a way. I'm sure that someone here has the Capristo test pipes and precat pipes and will have a photo of them before they were installed?
I wonder if your current setup actually flows better? (not having the precat pipes and cats....which add length and extra bends in the system)

So if I invest in a Capristo system, I would need to manufacture parts 57 and 58 in the above drawing and also a set of test pipes to replace where the cats would sit as I don't have cats either. Deciphering the Eurospares website has been interesting. USA spec 512TR comes with different exhaust headers to a Testarossa, but strangely enough, a South African early model Testa and a USA car delivered at factory share the exhaust pictured above with the only variance being the pre cat or straight replacement pipes. I wouldn't think that this will be difficult to fit up to the car. Making brackets to hold the spring bumper hangers will be the tricky part.
Yes, I feared it would be so. I don't know when it started, but, even in the 70's, different versions of the same model would have different bits of bracketry, holes, etc. on the chassis even though the overall design was the same. Or just make the single tube portion a longer length to replace both the precat and the cat with one assembly. Ferrari actually makes a stock part to do this. As you can note, items 57 & 58 both come in two flavors -- a shorter type (142166 & 142167) that only replaces the precat and a longer type (128589 & 128590) that replaces both the precat and the cat. However, all of these require the US/CH/SA length headers to work. Here's a shot of the 142166 & 142167 parts as mounted on my TR (although I have since sold them): Image Unavailable, Please Login "SA", in this case, I believe stands for "Saudi Arabia", not "South African" (and the SA uses the US headers). IMO, you'd be better off checking with Capristo to see if they make a muffler for the euro/standard version TR... JMO...
I am currently working on the adapters to fit an emissions style muffler to a non-emissions (euro) car. A few Ferrari parts are needed and the rest I am custom making. If any are interested please let me know and I will look into making more, and the cost.
Thanks Steve, great pictures. No Capristo doesn't make a straight bolt on for the Euro style exhaust on the earlier non cat Testarossa. I can't see that it will be too difficult. I'll have to fabricate some support brackets and the lower pipe sections, but your photos and other input will help here too.
Yes, pretty keen on this. Seems that there are a myriad of combinations of header length etc and that one of the more challenging issues will be how to mount the later style muffler to an earlier car that has no facility for the spring style buffer as shown in Steve's earlier postings. Aftermarket mufflers to fit the Euro cars have always been difficult to fit. All three of my cars have non factory mufflers and rely on a variety of really crap home made support brackets to hold them. Too much weight falls onto the small narrow waisted rubber bumpers and as the exhaust 'grows' with heat, these invariably tear and fail. The steel spring hanging support system is so much better and I've often wondered if something similar could be supplemented into the UK cars.
Rob, my Euro car has the spring supports to hang the original F muffler setup with no Cats etc. I am surprised if someone has gone to all the trouble of removing the bracket hardware on all your cars. The brackets are maybe slightly different to the US ones shown in Steves photos.... Image Unavailable, Please Login Image Unavailable, Please Login
Mike -- the PN shown on your muffler indicates that you have a very late RHD TR of the "GDE" version (SN 83374 and after). If Rob's RHD TR SN is below 83374, it won't have the same bracketry as yours.
Steve, as usual there is usually a reason, thanks. I am pretty sure Robs cars are relatively early 88.5 cars so that explains it !
Steve's correct Mike. None of my cars have those brackets. But I know a bloke with a welder. So if I had dimensions, drawings detailed pictures etc, I'll fabricate them and weld them on. I painting the frame next month anyway. One of my cars is late 87 and the other two are October and September 88.
It got a little crazy in the 1990~1991 timeframe with a whole bunch of slightly different version (GDE, CAT, BE) TR being introduced (in addition to what we have usually called "euro" and "US"). I think it corresponded to more of Europe (besides just Switzerland), and maybe Australia, getting serious about emission issues (and even though Mike's GDE version doesn't have cats mounted, they wanted to have the commonality so they could mount cats on the CAT version -- but that's just a guess).
Not so sure the bloke you know with the welder would have the skills that these Italian artisans have with their talents. It takes years of practise to get a weld to look as bad as they got them!
