Question GMMG + twin turbo ?

I posted this under external engine as well but thought it might get more views here and then i got another question in my head and it relats to FI. First off for people with the kit do you like it, and how is it holding up rust wise. Also would this be an ok exhaust to go with if the car had twin turbo. I love how the exhaust sounds but i didnt know if it would be a factor that it says its only 2.5 inches wide in diameter. I hope this question doesnt upset anyone being un FI. Just getting closer and closer to buying parts for the build. Thanx again guys.

Ive only just herd of the dumps. How loud are they since i will be driving this car on the street. also will they bolt up to the custom y pipe that comes in the kit. ive also herd that they rattle, is this true or it might have been a bad instal considering any exhaust will rattle if not installed prperly. any otehr information on these 4 inch dumps would be great aso where did you get your and how much did they cost.

I searched and i cant find anything on the dump tubes, is there anywhere you can buy these or do you have to buy universal ones and custom fabricate them on your car. Just to clarify i think i once seen a guy with the down pipe setup, are they short 4 inch pipes that bolt right to the back of the y pipe. Im not too clear on this setup. More information would be great thanx

For a forced induction application the less restrictions in the exhaust, the better it will perform. If you do a search in the external engine forum, there are pics of exhaust systems with a dump. It is just a short pipe that points the exhaust toward the ground.

would it be possible to run the y-pipe that comes with the turbo kit then run flo-pro twister mufflers off each end and get turn downs welded to the mufflers. Comments and suggestions would be great thanx.

In theory that sounds fine. I am not sure how well those mufflers flow though. There is another thread about different exhausts and how they seem to affect performance.
