Okay so here is the story. I currently have k&n intake, PLM header, Berk HFC, and invidia Q300. My wife finds the sound a bit annoying and I'm starting to agree with her. My question is if I swap back the stock exhaust will I still be benefitting from the other mods or will they be a waist?

 

How does your wife know what the exhaust sounds like? Do you drive the car in the kitchen? Ba Dum Tish (rimshot)!

 

swapping the stock exhaust back on shldn't sacrifice much hp and will def quiet things down

 

That should be a relatively tame setup. I'm surprised it's that loud. And you will be giving up most of the power benefit if you revert back to the stock exhaust. Then again, if this setup is untuned there won't be much benefit to begin with.

 

Yeah you will definetly lose a little power going from a 70mm to 60mm exhaust, and also bottle necking the system going from a bigger header/HFC to a smaller exhaust. Even with all those mods you probably didn't gain much without a tune, so you might not even notice a real difference if you swap the catback out back to OEM. So I would just swap them and not really worry about it.

 

Ya I'm willing to sacrifice a few hp to quiet things down. If this is tame I can't imagine wild. My TSX has all these mods and more and it's twice as quiet. Maybe I'm just getting old (37). I'm currently saving for an AEM ems. If I can sell the exhaust I can get there quicker

 

buy an N1

should quiet things up a bit.

 

btw that was 100% sarcasm.

if you couldn't tell

 

Keep exhaust, swap wife. Ayyyye

 

invidia is def a loud exhaust. if u dont want to sacrifice hp, check into more quiet catbacks like hks or fujitsubo or maybe even greddy
