I wanted to gather some opinions...

 

Love my GMG WC Ti Exhaust.

 

Straight pipes with 200 cell cats

Well there you go......it's unanimous as usual

 

^^ Hehehe

 

This is the cream of the crop from what i've read too.

 

Just to throw one more option to the mix...

Your muffler on the GT2 is a titanium Akropovic muffler.

How about leaving it be and just buy cat-delete in titanium from Akropovic themselves. Would make a for a great system I think.

 

I would also suggest changing out the cats. You have the top of the line titanium exhaust on the car already, I doubt the aftermarket alternatives would be better, I could be wrong.

 

Two things to know about the GT2. The exhaust diameter on the stock exhaust is 65mm. If you just replace the cats, you still are limited to stock diameter piping and 200 cells. No other manufacturer other than Europipe offers a 100 cell cat with no CELs...back pressure as low as 0.12bar compared to 0.4bar stock.
