I curious to get some thoughts about anyone who has this in their 996TT
Are the 100 cell cats sufficient or does it make more sense to do the 200 cell cats? (I've hear 100 passes CARB..not sure what to think)
Aren't the 200 more restrictive in power delivery? Or am I off base?
Does it also make most sense to do the headers at the same time?
Thanks for the info

 

do the 100 cel cats, and leave the headers alone. you dont need them unless you start making serious power north of 700 to the wheels.

 

Thanks for the advice

 

I have alot of reviews and videos here - http://www.vividracing.com/catalog/a...5-p-33955.html

 

Perhaps I can interest you in our exhaust system....

We use only the finest stainless steel with heavy duty flanges for durability and longevity. 200 cell cats clean up the emissions, and for off-road use you can easily switch to our cat-delete pipes for weekends at the track.

Contact me for more details.

 

Switzer, 911tuning, SpeedTech, BBi are imo the best out there.

 

There isn't one aftermarket exhaust system for our cars that is CARB certified. If you find a shop performing a thorough visual inspection, and you don't have the CARB certification = FAIL

 

You forgot Europipe

 

X2 on the Europipe. My favorite 996 Catback

 

This exhaust is art! I second the opinion of others here... Markski, Switzer, BBI, Europipe are my favorites... If I didn't have my custom exhaust built those are the ones I would have bought.....

 

pics of custom exhaust or ban

 

Really not much to see but here is a very old picture.... Built by Protosport... Not the prettiest exhaust but light, functional and catless....

 

Thanks everyone for the replies....like I had mentioned it is a tough but at some point I have to make the decission and move forward.

 

Oops!

 

We should run a 6speed report on the various systems comparing sounds, power etc....so many choices
