Default want HKS Hi Power Exhaust louder!!

Good day everyone ,

i have installed the hks hi power exhaust in my is250 , thought it would have been louder than what the youtube videos portrayed, does anyone have any ideas on how i can make them louder for instance removing the midpipe with the catalyst and installing the invida or megan racing mid pipe would make it louder? what are the pros and cons of doing this , if anyone has performed it i would greatly appreciate some reviews, such as gas mileage , noise intensity etc

Just install the Invidia mid pipe, if that's not loud enough, slap on ppe headers and call it a day.

HKS exhaust paired with Invidia Midpipe is probably the loudest exhaust option possible.

There arent really any drawbacks, only the fact that it sounds much louder because some people dont like their exhaust to be that loud.

I personally think my HKS + Invidia setup is still too quiet (for me) and Ive thought about getting headers but decided against it

do you have a video of your exhaust setup? I'm curious as well. I have a HKS exhaust as well.
