the car has been converted to a electronic ignition. so as of now the ignition is trouble free. not to say that it was perfect years ago. i have run into this problem with inline cats on other cars where the rear cat is in bad shape and the cat closest to the head is near perfect. cats are just funny like that. the motor is like a top on our car and never spits or hiccups. really a trouble free ferrari. if there is such a thing? |

I totally agree with you the sound is awsome.
Unfortunaltely, our lovely state of California smog regulations are never kind to our lovely classic Ferraris, which they were never meant to be choked up with cats. That is a painful reality and we all have to deal with it, if we want to keep our cars registerd. I must admit, those cats are not cheap unless you can find some aftermarket suppliers that would carry them.
Furthermore,I would seriously would check my iginition system if I were you to insure that you don't have a misfire. Cats would last a very long time as long as you have a good caliburated fuel and ignition system.
Blown cat indicates a problem and it is worth looking into to prevent future engine problems.

about 2 months after we bought our 308 we noticed that the exhaust note was quite different from one side to another. we took the entire system apart and came to find that one cat was like new and the other was basically gone. so i took out my trusty hammer and 16" flathead screwdriver and completely gutted the both of em'. replaced all the bolts,nuts and washers with new high strength stuff and bolted it all back together. sounds awsome. a little more throaty and alot nicer at highway speeds. plus the airpumps are gone so the motor is free to rev a little easier and have a few more hp. |

If any one is interested in 308 carb test pipes for in place of the cats, I have a pair of them that I had made sometime ago. I recently sold my 308 and the buyer was not interested in buying them do to smog reasons. I would like to sell them for what I paid for them which is $125.
They really made the exhust sound so much better and I miss my car greatly.

When you order the Stebro, you tell them which version you need (one nipple or two), so for my 308QV, it came with bungs for both the thermocouple and O2 sensor, just like the original cat. |

I have a factory OEM test pipe on my 328, it's straight thru with no packing, its slightly louder than stock, but I like the sound
The sensor(s) are for the O2 sensor and the other is a temp probe for the slow down light (overheated cat) which is not neccessary once cat is removed, I drilled a hole in the stud and placed in the 2nd test port to reattach mine anyway
The Stebro looks like it only has the port for the O2 sensor, the factory pipe has 2 ports one for the O2 the other for a test probe, I modded the test probe port on mine to accept the thermocouple (slow down light) probe |

Yes, the Stebro euro resonator has bungs for both the O2 sensor and thermocouple.
The reason that the Stebro units are less expensive than Tubi is that yes, their appearance is a little rough, the welds not ground down, and the stainless not highly polished. But for 308s and some other Ferraris, it doesn't matter as the exhaust components are not visible, so for most folks it's not worth paying for cosmetics on these. When I put on my resonator, the fit was perfect.

Austin 308, I'm in the same boat you're in. Anything you find out or go with please post or e'mail me.
Stebro's build quality looks rough. I handled some of their new products at Lyle Tanner's shop, ferraripartsexchange.com. I'm not averse to using Stebro's goods if I get some more input on the durability of their products.
I talked to Mike Kuhn at Norwood Performance, his comment was that the Stebro products look like "ham cans," but otherwise okay. The cost is attractive. Also from his info. their resonators have ports for the cat temp probes so you don't have to zip-tie your wires up...I need to get ahold of Stebro though to verify this...and make sure their resonators are available for the carbed cars.
I posted a similiar question under '308 cat/test pipe search' here as well...I'm still gathering the 'who has what info...' |

The wire is the "slow down 1-4" and "slow down 5-8" lights to warn when the cats are overheating. I just wire tied them to the frame rail.

The 'euro resonators' from Stebro (www.Stebro.net) have a deeper sound than if you were to use straight-through pipes. |

I've blown both headers apart since owning my '77 carb 308. We may have a set of tubes here if I can find the pieces. Didn't use either side for reinstall. Email JRV and see if he pitched them out (2 headers = 4 pieces!) |

Charles - make sure to get the correct length pipes - the carb ones are shorter than the FI cars (I know because I still have my first set of pipes -short ones-that didn't fit!) |

The cats on the car are due for a vaction. Where do you get the test pipes for a 308. What does the sensor in the cat do. Thanks Charles |
