Hello all!
I am a new member and have been slowing preparing to build up my 99 rs. I am looking at dropping a turbo on my 420a but the issue is coming towards the after market catback exhaust.

This is the catback that I am looking at: http://andysautosport.com/mitsubishi/1995_1999_eclipse/performance/exhaust/exhaust_systems/megan_racing/mega00087861.html

The issue I am having is that I want to prepare for the turbo system but am not sure if I should hold off putting the exhaust on until the turbo system is ready to go. I don't want to buy parts twice if I don't have too. Will this cat back work without the added back pressure for velocity from the turbo?

Thanks,
RomulusDSM
