del w/a gsr/B20 needs new exhaust > what would be the best aftermarket OR
custom-made sizing + muffler ( ex: ES tuning / Flowmaster etc...) should i get

 

get the apexi world sport 2 greddy sp2 or rsr ex mag. all quiet and nice systems. IMO the WS2 is the best of all.... rsr is expensive

 

greddy sp2 or spoon sports street. both good sound not to loud.

 

Get a universal WS2 muffler and custom piping.

You aren't going to find very many catbacks pre-made to fit a del sol.

 

the only quiet exhaust still being made for the del sol is the tanabe touring medallion. The apexi ws2 isn't made for the del sol period, and the greddy sp2 was discontinued 6 months ago. Finding a pre-made exhaust that isn't crazy loud is no easy feat.

 

thanx for all the suggestions > but i found out that the tanabe medallion
is the only one in the market thats ready to be hung w/o mods > thanx

 

you can go with a skunk2 megapower exhaust. it's a deep sound but you can always put the silencer in it to quiet it down.

 

The Greddy EVO2 is another good exhaust. I'm running something similar. Sounds great. But a a little loud for me.
If your still looking...

Looks like this on the car.
