LEVEL OF TAIL PIPES ON A 308 QV

I took all precautions and read all threads before installing my new X-OST and Hyper flow. Had to shave 2 donuts so the muffler would not be offset to the left. Now I realize the tailpipes are sitting too low in the openings of the exhaust cover. Is there any way to raise the tailpipes orientation other than ajusting the connection between muffler and catalyst??? Can I raise the side muffler attachements to the underbody (you know those funny supprts mounted on springs), there is an hexagonal nut at that level and I wonder if it is an ajustment for this purpose. Help! Any suggestion??? Thanks.

 

You ought to send it back and make them give you one that is correctly configured!

 

What year 308QV -- '83 (dual cats) or '84-'85 (single cat)?

Often you'll need to loosen/adjust the joints at the ends of the headers as well -- i.e.:

1. the ends of the headers are in a fixed position,

2. the muffler is mounted so the tips are in the right relationship to the coachwork -- which puts the muffler inlet(s) in a fixed position,

3. the joints and multiple pieces in between the two fixed locations are then adjusted to absorb the tolerances.

 

It is a single cat 1985. My impression is that the lateral spring mounted supports act as a pivot with the hook up to the catalyst at one end and the tail pipes at the other end . If I were able to lower the catalyst connection to the muffler by 1.5 cm the tail pipes would raise by the same distance. but to do so I realy have to change the orientation of the cat. and give it a downward angle... raising the lateral attachements to the muffler sounded so much simpler. The impression I get is that these spring-holders may be at a fixed (unchangeable) level. Darn! Any idea from Daniel Pass?? Thanks for your help. To be followed...

 

I have the same single-cat setup in my 1984 QV. When I took the stock muffler off and put on the Stebro, it was a perfect fit in both the horizontal and vertical. Something must be wrong with the way your new exhaust was made... and the manufacturer should fix it. You shouldn't have to do that kind of fudging.

 

lower the back of the cover.

 

You stole my line! LOL
