Curious if anyone knows of a good performance exhaust system without the extreme noise. B15. Entire exhaust. Header to tailpipe. Any suggestions. Thanks I'm new to this.

 

B15?

 

Sorry. D15b1

 

Leave it stock.

 

Yonaka makes a decently quiet kit for reasonable dollar value.

 

HKS Sport w/ a high-flow cat, it sounds great on the D15/D16. It also looks great and keeps an OE+ look.

 

theres no performance in the cat-back exhaust. just looks and sound.

performance gains are all in the header. exhaust manifold to cat. even a d16y8 v1 or v2 OEM exhaust manifold that is 4-2-1 is a great gain.

but if youre talking about modding your 1.5L engine, well i really dont think youll find any gains.
