Can you post the price for the decat version of the downpipe(just with the no cat. sleeve)? Also from the photo it seems (it might just be me reading the photo wrong) as the downpipe is a one diameter single pipe up to were it divides instead of a stepped design I have seen market that supposedly improve torque at low rpms. Care to explain the pros and cons for the different approaches if in fact they are different(straight vs steeped). I will appreciate your input as I will be making a decision soon for a 718 GTS downpipe. Thanks.
