I am thinking about getting the Stillen or the HKS Hi-power systems. These systems include everything behind of the cats, do I need to get a new y-pipe, cats, headers etc.? or maybe I'm reading it wrong and getting more than i think? Also will either of those systems give a cop reason to pull me over?

 

no they come with everything. cops can pull u over whenever they wan to.. so yes they can if you floor it with these exhaust. Under normal driving, they shouldnt have to.

 

Ok, so I don't have to worry about the other stuff, will these exhausts be sufficient should I want to add an APS or Turbonetics Turbo kit in the future?

 

I believe both are under the maximum DB reading that can get you a ticket...

 

The HKS Hi-Power exhaust has two resonators, which limit the sound produced to 95db . . . I think . . . And that is the legal sound limit . . . I think.

 

You are correct. . . . . . . I think.

j/k - I remember reading the same thing

 

What about having cats and headers...It's already pretty loud overstock... I have cats and soon to get headers but which exhaust will create the most torque?

 

your best NA power added with be a system that uses a Y-pipe vs. dual exhaust...those systems include Stillen, Fujisubo(sp?), etc.

 

In the latest exhaust shoot-out from Sport Z Magazine, the Stillen performed the best, but it also weighs 20 lbs heavier than stock.

 

if you really want an educated answer, PM DaveO...he's the editor for SportZ mag and he's very knowledgable on these types of things...

 

I am curious as to the db level of the stock sedan exhaust. I know 95 db is the legal limit but I am curious as to what stock is and what I might be adding for noise going to the newer stillen sedan exhaust. I hate like hell having to drive at 75 and having a drone sound or draw too much attention.

 

The Fuji exhaust weighs 35 pounds and the JIC Y Pipe weighs 11 pounds. That's my setup. 46 pounds total compared to stock of 70lbs.

 

sweet...so are we installing it here on the 3rd

 

Out of curiosity are you researching a G35 Sedan or Coupe exhaust system?

Im not sure when the FUJI will come in. It's an oversized box and takes longer to ship. I just took that weight measurement of the exhaust off the website. I weighed the Y pipe myself.
