Any thoughts on Helix DP/UP?
I have an SPT catback and I love the sound. In a year I would like to be a full TBE. For a awhile now I have been planning on getting Cobb's DP, but on their site they don't list their Uppipe. So I came across a place where I can get Helix DP and UP together as a package for $550 (this is catted version because I have to go through emission checks). Anyone have Helix partnered with their SPT? A lot of people say the Cobb one works well because it is a bellmouth and so is the Helix, so I wouldn't have any fitment problems right? If anyone has info on fitment, sound, and satisfaction from either the Helix products would be great, but if anyone could comment on their products with the SPT system would be great.
