GTM stage 2 TT with FI 3" CBE

Dembflyr

Like Chuck said, your car is not loud due to the exhaust rather it's due to the lack of one. When the WG's are open (when you are on the boost) the exhaust is bypassing the turbos. Your sound level would be equal to open headers.

Installing the GTM down pipes with the recirculating WG pipes is a difficult task to get it to align properly.
I fought with mine for months before I got them to align. I tried about five different times to get them aligned. I was convinced that there was something wrong with the pipes. Sam sent me a complete new set even though he felt that it was an install issue which it turns out it was. I went open dumps until I got them in.
Now that I know how to do it it would take me 2 hours tops to remove and reinstall.

You need to get the WG's recirculated. It refines the sound to an exotic level. Not too loud even under full throttle.
