I just can't decide what I want to do right now with my limited funds. Here are my three options:

Nismo exhaust plus,

Option 1. High flow cats
Option 2. Resonated test pipes and Pop charger
Option 3. Pop charger and plenum spacer

Which option will give the most noticeable gains for now? Emissions are not a concern. I hear that test pipes give off a bad smell, but is it really that noticeable?

Any input is much appreciated!

 

i think test pipes gives around 9-10, spacer is 10-13. and pop charger is about 6? these are all separate, i don't know how they stack up.

 

If emissions aren't a problem, then definately go with the test pipes and pop charger setup. You can also get resonated test pipes as well. Good Luck with your decision.

 

If I plan on using N2O later on, does it matter if I use high flow cats or test pipes?

 

Option 2. The Nismo exhaust isn't going to do much with the cats restricting the exhaust flow.

 

if you want your exhaust to smell get test pipes, if not get HF cats

 

Take it to jesus.
