muffler for the DDP

[ArmandoP]

Hey, I have one of your DDP's on my 89T... After putting on the big exhaust I want to keep the DDP effect, but I dont want AS MUCH noise. Do you have any ideas or maybe you can help me with some info on making or buying a muffler for the wastegate pipe?

[Shytheed Dumas]

I might have something for you, Armando. I bought a very free flowing 3" exhaust from MDC, but it was a bit loud for the wife. I pulled the muffler off and replaced it with a POS to get me by until I can afford a Tanabe or HKS Drager.

Anyway, this is a GOOD muffler - I believe $300 new, or so. It's got a small dent from mounting under the car, but no holes and works great. Comes with a few feet of mandrel bent 3" pipe, too. It's nice and small for an application like this. Here are the details I got from Jon:


As for the muffler,

I was eventually going to put this up for sale with a $125 asking price if it looks like it might serve your needs. Just an idea...

Ouch! That sucks....

A 3'' muffler is not going to work on the wastegate pipe. Try looking for a small muffler 1.5'' to 2'' to put on the wastegate pipe. Im not sure of how small mufflers get, but I have heard of some people trying motorcycle mufflers.

yeah Im looking for something for the wastegate pipe, I already have a full exhaust on the main part.
Ive found these two, strangely enough at the worlds largest catalog of tack on shit.... JC Whitney...

unfortunetaly they dont seem to show the piping size....

Ouch! That sucks....

Yeah, she wouldn't ride in it until I knocked a bunch of db's off of it. Thank God for SHM and Dragger's...

You know he sells a rerouted downpipe, right?

[bluemkiii]

Yup as joe said, just get it rerouted.

The wastegate piping size is 1 5/8" OD, one of those motor cycle silencers should work fine.
