Where to find "test pipe"?
 

I believe this 87 930 has the stock cat attached to an aftermarket muffler. And it looks very tired. If it had an air pump it is long gone. I was thinking it might be a good idea to get this lump out of there.

I noticed that the GHLs are not available on Pelican. Is there another source?

I searched and did not see any threads.

Any body have a used one?

TIA

I gave one to rarlyl8 a few years ago when he was looking at testing some. Check to see if he still has it laying around the shop...

Thanks JP

I was thinking about sending Rarly8 a note.

I found one at ****** for $250.....not bad..but for a piece of straight pipe....is there more to it?

If you're going to toss your CAT (good idea, by the way, it will make a huge improvement in your performance), then why not spend the money instead on a muffler that will bolt up directly to your turbo, like most aftermarket muffs do. There would be no need for a test pipe.

To me, the "test" pipe is an excuse to run without a CAT, and an easy way to put the CAT back on for yearly emissions testing. If that's the case for you, then buy a new CAT and a test pipe.

$250 and it's yours....

Then I built a straight pipe from a local autozone for less then $20 bucks and another ~$10 for an exhaust tip..

BTW - I sold my GHL because I wasn't happy with the finished product. The dual tips were not even. So what I did was make my own single outlet and bought a different valance. Much better....

I like the idea of a muffler that goes right to the turbo...and a Zork tube but that may be a bit anti social.

Thanks again!

The cat bypass tube will not do as much for performance as a free flowing muffler.
I do have JP's pipe but the air injection tube is mangled. Used it for testing.

If you can swing it, get a new muffler assembly. While the test pipe will help, the stock muffler is restictive and VERY heavy. I hear Rarly's are the bomb...

This actually has an after market muffler...but its big and heavy. I think it is a Remus. I am going to try to swing the Rarly option, he is almost local.

If anyone's interested, I have an old B&B twin outlet 930 muffler I'm tired of looking at.

can you send a pic? does it bolt right to the turbo?

Thanks
