I like the stock exhaust note but it is just too quiet. If I just add high flow cats, how much louder will it get?

 

Louder but not to the point where it will drive you crazy. Check out ours.

It will be BARELY any louder.

 

or get the fujitsubo legalis r

 

It made my brothers 05 sedan sound a littler louder and more aggressive than a stock coupe. Has the same sound as a coupe now, but just alot meaner.

 

+1 i jsut installed this

very pleased with it, very close to stock and nottoo loud

 

Theres also GReddy SP2, which is also just a muffler upgrade. High quality, sounds about the same and most likely has the same gains too... with a kinder price tag.

 

sounds good.........lets the car breathe a bit more........do it

 

Beware, you'll get a rattle coming from exhaust when you're about 2000-3500 rpm. I could not figure out what it was until i replaced my cat back with HKS hi power and it disappeared. Now i get a wicked wail

But anwway, it's supposedly because of increased airflow which the stock catback cannot accomodate? If you can live with it, then fine. I didn't like it...

 

Here's a sound/vid clip with Helix high flow cats and stock exhaust.
Sounds perty good IMO.

That is some funny ****!!! I can't believe people are doing this. But then again, look at the customers. He decides to show it off for the camera and drives on the wrong side of the road and blows through a stop sign... ...on camara.

And what's this fool talking about the only people complaining are the ones sleeping when they should instead be up cooking breakfast? You know damn well the people having these installed aren't even up before noon.
