Here is a post Woodster put up a while ago, great video:

 

I live in Laguna Beach and I have the Kreiss-Sieg exhaust with the bypass button on the dash. With bypass 'off', it is mildly raspier than stock and probably comparable to most aftermarket exhausts. With bypass 'on' it is a wild roar and MUCH faster (those straight pipes make a huge difference to the breathing of the engine).

 

I have the EP Stage II Loud and LOVE IT.

 

The best you can get is FVD! No drone and the best performance/sound!

 

Reading is fundamental... Just read the whole thread... There've been some interesting developments it seems, especially in the X design arena... Nice systems out there to choose from now... Depends on what you want...

subscribed, any UK owners on here with sports exhausts? Would be good to do a meet and compare/contrast.

cheers

 

I cannot comment on the other exhausts but I just got my speedtech excellerator exhaust on 3" and it sounds pretty good, definetly better then stock IMO. Good fit and finish and not to difficult to install.

 

i have an EP 2 loud and the sound is divine...such a great aggressive growl

 

so who makes the quiet exhausts? just the ep2??

 

We developed a quiet exhaust for those that desire the ability to carry on a conversation with a passenger, make a cell phone call or enjoy their favorite music. Our SpeedTech X-cellerator 2.5 quiet cross-flow design emits an exotic GT3ish sound and at WOT has a fantastic note, yet remains very unintrusive in the cabin. Video below.

For those that want an aggressive GT3ish sound, we also offer a full 3" X-celleratoir crossflow, as well. It's sounds very race-car like - like the car really means business!

I personally prefer the 2.5 quiet for my daily driver, it's a perfect blend of exotic sport sound and cabin comfort. With 100 cell cats and a straight thru cross-flow design, the 2.5 flows very well. I have driven both versions back to back with a typical 700 package - K24/18G's, fuel system, intake, TB, plenum, Y-Pipe, IC's, etc. and could not detect any difference in seat of the pants feel - I think it really boils down to how much sound do you want yourself and others to hear...

John, Id like to know how much shipped for the 3inch and the 2.5??

 

Dr. J,

Soon we will be firing up our 4.4L with an undisclosed amount of torque and hp (safe to say north or 1000) and it will have an EP exhaust.

 

SaikoE36,
