I'd say keep it since original lip is hard to come by and it's freshly painted. Brand new is over $600 a pop!! The cheapest knockoff Mugen lip is only hundred plus so just get it and save the CTR lip as a spare. You might get tired with the Mugen and realize that the CTR is better. It's original lip after all.
To all sifu, how come my fren's MR2 with Greddy Profec B2 boost controller maximum boost at only 1.1 bar. How come I can't boost over 1.1 bar? Stock Turbo CT26, stock exhaust.
