Because I do not see any boost creep on my '81 EFI engine with stock (Euro) WG muffler...
I'm trying to picture one of those. Got a photo?
What headers are you running on your Turbo?
(ps -- hope that arm heals soon!)

... only if it is a straight through design. Turbos don't like baffles.
Yep.

Hats off to how light you make yours being while still using stainless, Brian!

Maybe profighters muffler has some backpressure. I didn't have any boost creep until I modified the insides of my B&B single out driver side muffler so it's as free flow as it can be... and that was alot of work!

BTW I have RarlyL8 headers and muffler, so no restriction there

I run my car at Sandown here in Victoria Australia.
They have a 95db limit, with Brians mid range muffler and B&B headers I don't have any drama.
At the rear of the car its well over 100db but as they measure from a distance at the track its fine.

1991 C2 turbo

Brian B headers with a completely gutted B&B muffler single out - I'm talking hollow can

I found that the car was quieter (off boost) when I switched from stock header to Brian's
I assume from equal length - exhaust hitting ex/turbine with even pulses removing more sound energy ...

Any way Too quiet ! did not sound like a sports car unless you open waste gate .

I ordered a zork from Brian and will install soon.

motor apart due to broken head stud..going back together with Turbo Kraft proven Package

Tippy, as stated before you are more than welcome to try my old magna flow setup.

Finally some pics from my WG muffler. Unfortunately, I had some issues with the pic files, could only use the first ones. So I just can show these for now. I you look into the muffler from the outlet side, you can see something like a star in the tube

The star I assume is the crimped pipe end.

Here is my stealth tailpipe from the magnaflow. Dummy pipe sounds great on full boost.
