Exhaust Clearance on 5spd

[pato2002]

I have found a couple photos but no old posts addressing clearance of the exhaust down pipe at the transmission support after a 5spd swap. No one in the Houston group had interference problems but my down pipe is contacting the trans support after I snugged up the bolts. Is this typical or do I have something crooked? New motor mounts and trans mount installed. Trans supports were welded to the tunnel at the recommended 80mm above frame rails (which also put the trans about 3-5mm from top of pounded tunnel). Driveshaft and giubo aligned with a few washers under the CSB mount. I marked the trans support where it appears a semicircle needs to be cut out but wanted to check with you guys prior to cutting. OEM downpipe (47mm OD) and cast manifold.

What downpipe are you using? You need one from an automatic or IE’s Stainless one.

The original one for a 4spd. I guess I either have some purchasing or cutting to do. Thanks.

I had to notch my shortened 4 speed transmission mount on the 73.  The bracket interfered with the exhaust (stock tii components).

Here is the original configuration using the 2002 Haus U-shaped bracket.  No interference with the exhaust.

 

I changed the rear support in 2012

Man that looks tight tight tight! Just curious any rattling?

None.  I even have stock engine mounts (and the e21 tranny mount).

I ended fabricating a new trans support out of angle iron and with a semicircular cut for the exhaust. Bolted up nicely with 1/8-1/4” gap. Time will tell if it rattles but felt good when I tried wiggling it. I’ll post a photo later. Thanks for the support.
