if you dont get his goto autozone and get a spectre pipe and whatever 3inch cone you want. Dont get the apc thing because it has an extra sensor hole with no plug.. the spectre comes with a plug. Cut it down some (not sure how much for elantra sence I had mine in an accent first). I do know at the length mine is it doesn't bounce the filter on anything and it has no mounts.
I wouldn't have tried to take sales from you... but sence your shutting down ill plug the autozone special intake. Pipe is like 30bux I think.. the generic cone thing costs 20. I went with K&N so I just had to clean it. No diff in power between the generic and the k&N.
