Celica Forums General Discussion General can I swap exhausts?

I just bought Greddy evo for a gt, but now I am getting a
GTS and I was wanting to know if I can just swap out the stock exhaust on the GTS for the Greddy I just put on the GT? If so, why do they sell exhausts for a gt and for a gts, instead of making it fit both?

It wont fit 'cuz the diameter of the GT exhaust is smaller than the GTS exhaust. Tanabe is the only company that comes to mind who makes an exhaust that fits both GT & GTS.

ok thanks. too bad I just wasted $540
