Oops, I was afraid that would happen. Lets see if the pictures come through this time.

I've finally given up. Tried everything and can't get the system lined up. The tubi mates up pretty well with the exhaust headers although fit on the one toward drivers side is very, very tight. Doubt that I could get the gasket between the two due to interference of tubi with frame member.
In anycase, the problem is more to do with the tubi mounting brackets and the chassis mounts. The tubi brackets are much higher than I think they should be and I see no way to connect them to chassis mount without major modifications. Further the drivers side mount actually interfers with a rear frame member.Below is a picture first of the tubi system as received and the second picture is of my attempted installation showing the interference of the bracket with the frame member and its relative orientation with the chassis mount.
Anyone else out there with a tubi have any comments on this system in the system and does it look correct for an 82qv.

I'm not sure if this helps you or not but...
I have a 328 Euro (which should share the same exhaust as the 308QV). If you reference the two bolt exhaust mounting(centerline) on the passengers side of the exhaust, the output tips(centerline) are 1-1/2" above this. The chassis mount is 3-7/8" above the two mounting bolts. The inlet pipe(centerline) is 1-1/2" below the two mounting bolts.
Hopefully this should give you some reference to another car. |

Jeff/Bret, Thanks for your help. Got the axle out of the way to slip the exhaust past it. Unfortunetly it soon became obvious that the system Tubi supplied will not fit up to this car. The rear mounting bracket on the drivers side has a significant interference with the car frame not to mention the there is no way to attach brackets from these mounting plates to the original mounting points on the car.
I kind of expected a problem just laying it out under the car last week. Called tubi and they feel it is the right one for the car. They were actually quite responsive although still can't figure out whats wrong.
Dead in the water here in western NY with the old system out and the new one not fitting. Oh well, their calling for snow showers this coming week anyway so I'll be looking for another exhaust system to try. |

Tony, the allen bolts do have to come out. They're tight and kind of a •••••, but can be done. Hardest part for me was the fact that you can't get a wrench around the nut on the backside due to the taper on the hub flange. I didn't particularly like stressing the flange by having it hold the nuts steady, but ended up doing it that way. As Bret said, use an allen socket and breaker bar. Once they're off, I lightly hit the edge of the CV joint with a block of wood to separate it from the flange. It will press back onto the axle enough to clear the flange. This should allow you to moveit enough to get the pipe through. Putting things back together, I still didn't like the idea of stressing the flange, so I ground down the ends of a 17mm open end wrench until it would grip the nuts reasonably tightly. I was able to torque them all to the proper torque except for 1 using the open end wrench to hold the nuts. Just couldn't get that last one with the wrench and ended up torquing it against the hub. Oh well, principles got overwhelmed by the reality of Italian engineering. |

The Allen head bolts are tight as hell, but easy to remove. I broke them lose with a 1/2" breakbar and a allen socket, then used a 3/8" air gun to pull them out (just take longer by hand). I had to break the inner ones loose though to separate from the engine, should be same procedure for the outers. There are washers (odd shaped, like a half circle and goes to several holes) in between the damper/where the bolt goes in and the diff, I would imagine this to be the same on the outside. You have to break the one at the hub since at the engine wont give you enough clearance as far as I can tell. Once you get it broken lose there really isn't anything special going on in there. Just packed with grease, the CV is on the otherside of the bolting place. The point of my rambling is that it looks worse than it is, and some time and cursing about Italian engineers will get it done.
I'm not sure how the euro exhaust works for your car, on my US version this is where the two headers meet and then come to one pipe and out under this half shaft on its way to the cat, then to the muffler. |

Thanks Jeff. Can you tell me exactly what had to be unbolted from the outside end of the driveshaft to move it out of the way. I hope it's not those allen head bolts I'm looking at.

Don't know about the mounts. Haven't received my tubi yet. |

I was hoping that didn't need to be done, but so be it. I know what I'll be doing tonight.
I still don't see how I will be able to mount system to existing mounting points using original brackets, etc. Is there some modification required to OEM mounting points? |

Don't know about the 82QV but with my 77 which also has the euro style exhaust, I was able to remove the old system with the car on jack stands. I needed to unbolt the outside end of the driveshaft to allow the flange and bend of the pipe to clear the a-arms. |

Just purchased a tubi exhaust for my Euro 82QV. But it appears from laying it out under the car that the mounting points on the tubi are much higher up than the original mounting points on the frame. I now wonder whether I have the right tubi for the car since I was told that it "uses" OEM mounting points.
Has anyone run across this problem and what is it I'm mising?
Also, I have come to the conclusion that the car will need to be up on a lift to install due to a tight bend where is passes under the passenger side drive shaft.
Anyone been able to do it without having it up on a lift? |
