2000 NB Test Pipe Help!
 

Bad Idea

who told you you need a test pipe and why

On NB's the cat is part of the mid pipe. You can purchase a catless midpipe, or cut the cat out of the stock midpipe and weld in a section of pipe in it's place.

Ok thank you, Would this throw an engine code?

Hi. I'd like to pollute orders of magnitude more than I currently do for no performance benefit on my otherwise stock Miata, and I'd like to spend time and money in order to do so.

Can you help me achieve this, because I'm a moron?

Not only that, but it will sound like garbage too.
This n00b might not last here. Just too stupid.

*edit: love his edit and revenge neg prop too :laugh:

Be careful bro, you've got 23,000 other posts he can neg as well :noes: :laugh:

OP: If you are still on the stock ECU, the cat makes zero difference. There are minor gains are to be had on the intake side and almost nothing on the exhaust.

The key to making any kind of N/A power is ditching the stock ECU and getting something programmable like a Megasquirt or AEM and having it tuned within an inch of its life by someone who knows what they are doing. ECU + wideband + injectors is the foundation for all future upgrades.

Such as turbo :party:

Thanks, I now understand that. I just had a simple question didnt know everyone else would flip out.
