You can get a test pipe for less than $300, and even that isn't much help and very polluting ...
So why spend the money on a less restrictive cat ? And I doubt the cat is bolt on ... that means getting someone fab and install a new mid pipe ...
You can spend it on a exhaust, I think the weight reduction is better than the performance gain ... the OEM exhaust is heavy, I got one hanging on my wall ...
but to me, exhaust mod is mainly perceived gain due to higher exhaust noise, I rather let those single digit HP gain alone so I can have a conversation in my car without yelling ... |
