That's a turbo car right? So the exhaust will sound moderately different on a blower car...

Tips looks excellent and a unique design.
 
Looks very nice!
 
Beautiful tips. Look like the same tips that are on my GT500 Corsa cat back.

How much uninstalled?
 
Dave, yes that is a turbo car. I'll get some clips of one on a blower car shortly and post them here.

The system with hardware and removable baffles sells for 2299.00

Thanks for the compliments. Not to pat ourselves on the back but yes, we really like the tips as well.
 
Awesome !!!!!!!!!!!!!!!


Damn you Gary !!!!

You trying to make me spend more money ??? :lol :rofl :rofl

Removealbe baffles? Can change for sound changes or less noise, or an all or none deal?
 
Looks great! Theres no way of welding those tips to an Accufab is there?
 
Wonder if these larger tips get too close to the plastic shroud in the bumper to melt the plastic? Any thoughts anyone? Actually, someone needs to make a more heat resistant shroud for the tips.
 
The tips look great! I assume that the tips are doubles walled near the end that would help them stay much cooler than the exterior single wall tip. Also they may have a chance on not blueing from the heat.

Where are the baffles in the pipe? Are they easy to remove and install?

Dyno data?

Is dyno data available? Before and after runs on an otherwise stock GT.

The tips are about the same distance from the plastic shroud as the Ford Racing Borla muffler tips which have not been an issue with my car. I'd expect with the exhaust pipes exiting about an inch farther back than stock or Borla this would help things as well.

How easy are the sound baffles to install/uninstall?

Looks like I'm going to be sending some coin to Sarasota...
 
Hi guys,

In order to remove or install the baffles you would need to unbolt the exhaust system at the flange where it meets with the factory exhaust or aftermarket headers. There is only one set of baffles so yes, it is an all or none type of thing.

This system will fit the FRPP headers as well.

Like Chris said, the tips are the same diameter as the FRPP tips and are double wall so the outer wall of the tips will stay much cooler than single wall tips. Like Black Ice said, the double wall tips are also much more resistant to discoloration that any of the single wall tips.

We will have some before and after dyno data in a couple of weeks when the first full production run is complete.
 
How much of a difference in sound and loudness of the exhaust with and without the baffles. Is the demo sound clip with, or without baffles?

When you tune a car with or without baffles do you need to retune if you change the configuration? How much do the baffles affect power output?

BlackICE
 
So far we have only tested this on a turbo car and there was no power difference between baffles and no baffles and there will be no change in tuning required between the two. The video clip is with no baffles. The baffles don't make a dramatic difference but it is noticeable.
 
We need to hear this combo. Someone quick, buy it...
