Brz More Noise Advice
 

So i have the 3.0 inch Xforce cat back system installed on my BRZ and sounds great for a second when u turn it on and its cold then warms up and shes quiet again so im looking at how to make more noise
some options i have thought about is headers which are $$$$ or catless front pipe
but long story short Im looking for advice on what's best bang for my buck as car parts in NZ aren't cheap

Remove the exhaust and header.

That'll do it!

Yep LOUD and obnoxious. You will fit in well here.
