Is it possible to move from stock exhaust to something like a Corsa Extremen setup and still retain the dual mode (mild to wild) capability of the stock exhaust? Tried to search for the answer, but came up unclear.

I have 1 3/4" LG long tube headers, in case that changes the answer.

To my knowledge the Billy Boat Fusion is the only exhaust that will still use the mild to wild. I am pretty sure Corsa and borla dont have a system like billy boat

I was considering the fusion but I honestly can't afford an exhaust at the moment so I am doing the muffler mod now that this crappy winter is coming to an end The BB fusion is a SWEET looking set of pipes though! I'd love to have a set

tonypittman

Thx. What kind of muffler mod you thinkin of to fill the bill..as an alternative?

Here is a thread about the "muffler mod" which is a very common mod among Z owners. An aftermarket exhaust doesn't add much power for the money so to gain a more "throaty" sound here is what a lot of guys do....

I'd love to put a set of Fusion pipes on my car but money is tight. The BB is such a pretty system! I want to get a new cam or save up for a blower instead so consider the muffler mod if you want to save over a grand. It sounds real nice!

Thanks again. This post on the Billy Boat Fusion exhaust relates to your point.

Hello, maybe You were interested in this http://www.youtube.com/watch?v=xUgV0GTo0FQ

This is completely new exhaust solution (there is some kind of prototype on the video, as finishing is secondary) Made in Germany, the vacuum actuators are taken from Porsches, price tag is 2k Euro

Looks, and sounds, great. Are they for sale yet? So far, the only dual mode I have seen for sale is the Billy Boat Fusion.

The factory system (with the cheap mod) and some LT headers/high flow cats sounds really impressive plus you get about 30+ HP/TQ gains for about the same cost as a cat-back exhaust.

There are many vid/audio clips available. That seems a more cost effective way to improve the exhaust note and gain some added muscle.

Yes it is, sales running since end of February. They have HQ in Switzerland http://www.loma-motorsport.com/loma-...sport-auspuff/

It should be much louder and lighter too.

Roger at TQPE; here in Houston, makes a system that has dual mode functionability. I believe the price tag is less than the B&B setup. Roger performed the Muffler Mod on my 09 Z06 and I could not be more pleased with his work! Two thumbs up for TQPE! here is his web site: http://www.tqpe.com/

Good luck!

Why not consider electric cutouts? They are a fraction of the cost and sound amazing!

I just put a pair on a red C6Z! The owner loved them considering he only paid $550 installed...

They do make exhaust systems that utilize the factory mild to wild system. They are expensive though...

I saw your car at the show, looked great!

tonypittman

Thanks, man. Glad you made it out.

Where can I get more info on the cutouts....how they install, how they work, etc?

Many states, including mine, have laws against electric (or any other kind) cutouts. I suggest you check this first.

The OP got this sorted out about 5 years ago...

On a 2010 Vet Grand Sport, is the Duel Mode Exhaust located in the rear with flappers in the tips or on the exhaust pipes before the converters? What year did they make the change? mike

MTPZ06

Wow, another revival on this one.

The valves are located between the back end of the muffler body and the exhaust tip. As for what year a change was made? Are you referring to the 4 cat setup versus 2 cats? If the GS followed the same timeline as the Z06, the '12/'13 models received 2 extra cats at the front of the mid-pipe. Corsa sells an x-pipe that deletes them for the Z06...assuming they have one for the GS as well.
