hey guys...im getting an apexi ws2 catback and a DC 4-2-1 header for my 98 civic SI, the problem is its a candian model SI so apparently i have to order for an EX ...should i buy off ebay and save some money but risk getting the worng part etc... (and if so, what are the best ebay stores to buy from)

or should i just get them from authorized dealers here in Calgary?

I'd be saving about 170$ for both off ebay...but then the part is not backed very well etc...what are ur opinions?

 

feedback ... best part of ebay. As long as the seller has a good feedback i wouldn't worry about it too much ... thats where i get almost all of my stuff

 

I dont really trust buying alot of car parts off of the internet like to make sure im getting the right thing. and in your case i would buy from a store since it sounds like you may run a high risk of getting the wrong part in your situation. Talk to the people at the stores around you about it. But if i knew it was the right part I would just check feedback on ebay and maybe go that route.
