I met SuperUser (Daryl) today and bought his FVD Cup Pipe. I also got to see his sweet '90 cab.

The install took right under an hour. I thought I'd be able to remove the muffler without removing the bumper or the heat tube, but no luck.

First step - Get the rear end on ramps or jack stands.



A shot of underneath the car.




Picture of the clamp on the secondary side of the muffler. Remove the bolt and slide the clamp towards the secondary muffler. Then remove the exhaust donut.




Picture of the clamp on the cat side of the muffler. Remove the bolt and slide the clamp towards the cat. Then remove the exhaust donut.




Couple of pictures of the clamps unbolted and slid away from the muffler.






Remove the 2 allen bolts from the muffler strap. Then slide the straps off of the bracket behind the muffler and then out away from the muffler.
At this point, the muffler would fall out if there was enough clearance but there isn't. I decided to remove the heat tube.
Remove the hose clamps from each heat exchanger and then the clamp from the rear tin that connects to the top side heat tube. You will then have to move the muffler to one side and push it up to get to the 2 M6 (8mm wrench) bolts that secure the heat tube. This was the most frustrating part of the entire job.




Here is a shot of the heat tube a muffler removed. Don't let either one fall on your head.




The heat tube reinstalled




The Cup Pipe




Installing the Cup Pipe is a no brainer. It is a direct reversal of removing the muffler. Connect the ends to the cat and secondary muffler. Installed the straps to the bracket and pipe. I have to remove the bottom shield from the cat which if you haven't done it before, it might take a while because the nut clips will probably strip out.

Glad you got it on. Wonder why I did not have to pull my bumper when I installed it. I just unbolted the primary and rotated it a bit and it dropped out. Getting the primary back in was a bit harder but I still was able to do it with out pulling the bumper. Did you get a chance to drive, I bet it sounds great in a cab!

The car sounds incredible. From the start up idle to WOT runs. I'll see if I can take a video and post it this week.

I tried every which way to get the muffler out and it needed another inch of width between the heat tube and the bottom edge of the bumper.

His wife knocked some sense into him and told him to keep it.

I also had no problem, did not remove the bumper or heat tube.

Thanks Mike for the great photos and write up. Also bookmarked for the winter when I hopefully will get around to installing the cup pipe I have sitting in the garage

Good to know. The bypass will be cheaper.

Damn, I contorted the muffler every which way and it was too fat to squeeze between the heat tube and edge of the bumper.

Just did the same upgrade this weekend...hands down the best "cheap" upgrade so far.
Pretty simple straight forward procedure that Mike has outlined very well.
Car sounds fantastic and dropped 20lbs, you can't beat that.

I had a Cup pipe and de-cat fitted last week to my 964.

Took it out for a few hundred miles this weekend and all I can say is wow! Burbles along without issue in 5th, but drop it down a few cogs and it sounds like an earthquake!
