turboxs turboback exhaust noise

[Trogdor]

I just installed a turboback exhaust from turboxs the other day and i love it. its a huge improvement. the only thing is that i can really hear the turbo spool up in the car. and you can hear it outside the car as well. i'm not complaining about the noise, i just want to make sure that it is normal for it to be so loud now.

oh, also i was wondering if it would be worth the effort to wrap the exhaust(headers, up pipe, down pipe)?

the loud turbo spool is totally normal

wrapping the downpipe immediately after the turbo wouldnt be a bad idea, where the heatshield used to be. protects a bit from intercooler heatsoak. other than that no wrap is necessary.
