Will the addition of a y-pipe improve performance of my car
even though I don't have a full catback? (I've got HKS)



What type of gains should i expect with an aftermarket y-pipe,
a R/T Cat Convertor and the HKS rear section?

And also.....how different will my car sound?

Thanks guys...

 

y pipe adds 8 - 12 hp
catback adds 2 - 4 hp

you do the math..

car will sound nice and quiet without the catback..

lots of us have y pipes alone.. better gains... sleeper look

 

Thanks Sprintmax!!

hey I was wondering....I've got the HKS rear section. If I
put on any aftermarket y-pipe won't it sound a bit louder?

 

yup.. the aftermarket muffler or catback will sound louder with the y pipe.. most people think its the y pipe that makes the muffler/catback sound loud.. but its just because more air is flowing..

see most people do muffler/catback before y pipe.. but if you did it the opposite.. you would notice how quiet the car is.. and its actually the muffler and catback making it louder

 

I use to have the HKS with my y-pipe and it was dumb loud for my taste. Sold the HKS after 1 week.

thanks again Sprintmax for the help!


Hey Cisco!!

I heard it get's A LOT louder with the greddy catback.
Is that true? I mean...how much louder could it get?

anybody know?

 

I'm sure it does get louder with the Greddy system. I had to take my HKS off cuz it was giving me a headache from all the droning.

I heard the HKS on the MAX , INSANE amount of Sound .

Way too much for a luxury sports car, Its better to have power then sound.
