Im down to 2 exhausts, anyone have these two or have any advice to swing me either way... thanks

Greddy PE or Apexi GT spec

E.J.

 

Definitely the A'pexi GT Spec.

 

Apexi N1 all the way baby...!

 

i ahve a gt spec and love the sound and performance... the 3.75 is great...... also i have a used one for sale 600+shipping

 

Apexi GT! It just sounds mean.

 

The exhaust does have a very good tone to it but it is way too loud. And i'm running it with the stock cat.

 

Does anyone know how much they weigh? Power extreme, don't like the sound of the Apexi catbacks.

 

I would sugges the GReddy PE. I didn't like the sound of the Apexi, but it's still a very good exhaust. You can't go wrong with either one...

 

Apexi GT sounds great and has awesome flow to it. I have heard some others but it's got the best sound IMO.

 

GT Spec....IMO its not that loud, maybe at WOT, but it comes with an optional silencer. I have it on my R1, and love it.

 

GT spec, PE sounds like a honda.

 

anyone know where to find sound bites of these exhuasts?

 

i have the pe and it doesnt sound anything like a honda. its not that loud and it flows good.

 

Unless you're a weekend racer and don't care about performance on the street, I just don't get the point of these silencers. From everything I've read, they rob the car of some pretty serious power. Why would you get an exhaust with mad flow and bone-rattling volume and then put in a silencer which robs it of both, when you could have an exhaust like the PE or Racing Beat which flows pretty well and is actually livable without any power-robbing silencers?

JDS.....I don't use the silencer because of the reasons you state. I just through in the fact that there is one available.

 

gt spec!!!

 

thanks guys

 

Some of us, including myself, NEED the silencer to keep the turbos in check. With my setup, even with my boost controller, without my silencer I cannot manage my boost AT ALL. Therefore it is necessary for some of us.

 

No kidding...I hadn't thought of that. So you get spiking, or creep, or both? With the silencers in do you still get rapid enough spool-up?

I get mad spikes. I can set my boost controller at 2psi and with my silencer out hit 15+ psi. Kind of scary, but the silencer is what keeps me safe from spikes. Very useful in my instance.

 

Interesting...the EVC doesn't allow you to keep a boost limit (forget about spikes for a sec) lower than 7 psi or so does it? Most of the controllers can't keep it below the wastegate spring pressure, but maybe HKS did something different. At any rate, does it have any sort of attack adjustment, or do you just set your max boost and that's it? SCC did an article a while back on boost controllers and which ones helped with spiking, etc...but I don't remember how they rated the HKS, or even if they rated it at all.
