turbo 6 bangers post here

Ok, I'm planning my exhaust right now and I'm trying to figure out what size piping I should do (I'm eventually going turbo and I don't want to redo my exhaust) and its between 2.25 and 2.5". Also, I'm going to use a Magnaflow glasspack and I wonder if I should get one glasspack and Y it off after it, or Y it and go with 2 glasspacks (one for each pipe since Im having dual outlets). If anyone has any insight on this, please let me know. Thanks!

I have no insight to share, but I DO have an opinion...

My opinion is that, once the turbo is an operating part of your exhaust system, you probably won't NEED a muffler... Turbochargers homogenize the sound waves in the exhaust, and quieten things down to a large degree. You might want to run a 3"-dia. pipe out the back (from the turbo) but, I doubt that you'll need any more silencing than that.

I wouldn't use pipe any smaller than 3"... Tubos really appreciate a free-flowing downside...

Just my 2-cents...
