This past week I installed a DNA Catback Stainless Steel 2.375” Exhaust made for the Si, which I got from eBay for $175 shipped. Install was relatively quick and lined up perfectly, only had to trim a little bit of plastic from the bumper.

Exhaust makes no drone, is quiet on idle but comes alive around 2-3k rpm with small pops/crackles, without being to excessive. Downshifts and quick revs have deep and aggressive tone. Unplugged ANC module behind glovebox to prevent unwanted frequency and seems to have made a noticeable difference.

Also installed a K&N cold air intake, purchased on sale for $360 and it’s been well worth it. Noticeable power gains, very loud induction noise above 4.5k rpm and really makes a night and day difference when you hit vtec.

Install was quick, fitment was perfect, finish of the powder coating and heat shield were top notch and thoroughly impressed with its performance/looks.

Attached YouTube video has clips of start-up, revs, launch, accelerations, downshifts, and more. Any feedback is much appreciated.

 

very nice brother.
