What is the length of the test pipe section, flange to flange?

I'm in the process of procuring the materials to make a resonated test pipe using the largest resonator available (26") if possible. I would really like to eliminate as much drone as possible. Having a catless setup makes this challenging but I'm going to do what I can.

Currently drone is nonexistent with only a Greddy CBE, but I know that will change after I install the DP and TP. Also, I'm looking at getting a DP with a flex section but I've never had an exhaust with a flex section so what should I expect in terms of sound? Will it make any discernible difference?

 

why not just buy one? I mean i have the ets resonated test pipe and is only slightly louder at wot then then when just the cat was in.

 

Because it's just a straight pipe with a resonator for $300-350. I can have one made for $100 utilizing a 26" resonator instead of a 12 or 18" one.

The one thing I need to find is a source for a CEL fix bung.

 

Vibrant J-bung


Also, options for excellent quality resonators.

It's not just a straight pipe. If you weld it up straight, it will rub on your driveshaft. You need to angle it slightly to clear.

 

You can pick up a test pipe for 100, no need to make one

 

Great info
