Welcome from Longview, Texas.

Number of exhaust options.
Which I narrow down to: i Lotus Sport..., ii Larini Club Sport, iii. (i) or (ii) with 3rd CAT delete, iv Plackslayer straight pipe. Ranking from i to iv in increasing sound and decreasing weight. Personally I like the deeper resonance of the Larini.

GT rear wing, two I know of... From Lotus Racing (contact Allen at VSA Motorsports in Cali.) or Mansory Design version, you would need to search for dealers.
