Hey Che,
I'm a little confused about your site.
The only exhaust I see is this item (
http://www.topspeedauto.com/ProductCart/pc/viewPrd.asp?idcategory=293&idproduct=2222 ), but on that page it says:
"Race Version for Track/Race / For most People is too Loud for Daily / Street Driving"
Is that item the race version or are you saying there's a race version available ?
Also does that exhaust throw any CEL when combined with this header (
http://www.topspeedauto.com/ProductCart/pc/viewPrd.asp?idcategory=293&idproduct=2245 ) ?
Thanks!
