    I can't help feeleing that the car became slower after replacing the shorty headers with HiPo manifold - am I dreaming? Latest: The Dynomax VT's have arrived at the post office, so they will be installed soon. I will report results then.

    Time to upgrade exhaust

    The VT's are last resort. Today we will open H-pipe, and open the holes in the two main tubes (they are very small) in order to increase crossover flow. I will report how that works. Another tip we got i n order to reduce drone was to move one of the mufflers a couple of inches forward...

    Time to upgrade exhaust

    Update We will replace the two Dynomax super turbos with the new 'drone free' VT's Also we will cut off the H-pipe, enlarge the (small) holes in the main tubes, and make a H-pipe with an oval 2,5" pipe. Our theory (partly made from advise from members of this forum) is that this will...

    Time to upgrade exhaust

    Not so happy after all.. We finally got: - shorty headers off, and HipO manifold on. - Rear transverse muffler off, and resonators on - new prefab 2 "H-pipe and tailpipe from NPD However, we didn't get the mid section pipe in 2" so we used 2.5 " The H-pipe had to be cut and spiced in...

    Mixing dimensions - exhaust

    Thanks. I thought maybe the path with wider dimension could create a chamber causing boom / drone effekt

    Mixing dimensions - exhaust

    We are mounting new exhaust now and we have threes sets of tubes: 1. H-pipe 2" 2. Tail pipes 2" 3. Pipes 2.5" between H-pipe and mufflers (before tail pipes) Are there any problems mixing dimensions (sonically or performance wise) ?

    Engine mounts '65 -> '66 replace problem

    We have changed from 1965 type mounts to 1966 type mounts. After replacing the mounts (with a lot of hassle) yesterday we found that the engine had moved approx 1 cm ( 1/2 ") forward causing clutch fan to touch fan shroud. What is wrong?
