Good used test pipe

[Randy Hagins]

Looking for a good used test pipe for my '87 GN. I still have the stock down pipe. Thanks in advance!

www.kirbanperformance.com has both a test pipe and a dump pipe for stock downpipes.

If you can't find one or don't want to make one.

You're welcome. It makes it easier to help when you include what DP you have as there are many and are different lengths which require a different length of test pipe/ dump pipe.
That was the first mod I did to mine, the one I made was just straight to the 4 bolt flange w/o the bell. I don't think it mattered at that power level though.

I did in the original post, I'm still using the stock DP. This is my 3rd GN, just got it a few months ago, slowly building it up. Thanks for the info!!

Sorry, I was complimenting you on including the correct info to make helping easy.

Congratulations on your third GN, I'm still working on my first one. Lol.

I had my last one (which is my profile pic) for 10 years, completely went trough everything! Paint, motor, trans.....had to sell due to divorce 6 years ago. I certainly didn't want to sell, I HAD to sell. Put so much time into it. I bought the one I'm building up off a friend of mine that is the original owner, car sat for 6 years so it needs some cleaning up and maintenance. Car has 42,000 miles, I plan on building it up like my last one. Might take a little longer but I'll get it.

Nice. Sounds like a good plan.
