Actually what I'm more interested in is how it tapers down? Is it 4" into a muffler and 3.5" out the other side?Please note this isn't a piss take impellor.. Actually curious.

Tapers down to 3.5 just before the centre muffler. 2 Link to comment Share on other sites More sharing options...

Wrapping sections of it or an additional muffler to keep temps up? Link to comment Share on other sites More sharing options...

I asked about a GTX3582r but that requires other work.. Iv read some big number on here with the standard turbo from the F6 so hopefully I'll get there with the mods I'm doing.. 2 Link to comment Share on other sites More sharing options...
