with 45 bucks i'd just go with a test pipe. screw the environment lol and it doesnt smell half as bad as everyone thinks/says it does. anyway if you wanted to go brand name i'd agree with the guys here, berk seems to be a popular choice as i was looking into it myself until i realized i could just pick up a test pipe for half the price and if i'm right the test pipe is 13% more efficient? someone check on that number please...

 

mm... no, the SARD is a metallic 200cpsi cat.

I wonder if the (probable) extra build quality is worth the price..

the SARD has a heat shield plate (I do not really know if its really necessary thought). it's built with SUS304 SS for corrosion resistance (well I suppose the Berk is more or less that quality as well).. and they write something that is plated with precious metal (gold?) in order to improve the flow (whatever...)

 

 

The title is misleading. That's a resonated testpipe.
