I have the sport system with the dual tips. I don't think they make a dual setup. As for sound nice and quiet outside has a nice rumble that gets you a look. I also run a volant cai. Price wise your looking at 700$ plus.
thought that I would add this ,also just got off the phone with summit for the 02 avalanche they gave me this part # 14260 and a price of $687.95 for the corsa sport system.
ok here goes called corsa tuesday morning ,they gave me part number 14260 ,then I called summit gave them the part number they gave me a price of $687.95 ,after getting home tonite and reading your post I called summit again ,they claim that corsa gave me the wrong part number, new part number is 14250 $750.95 ,that also will be the part number for yours,this is for a corsa sport cat.back.
