stupid exhaust question....

[Eagle9119]

so i feel pretty stupid for asking this. but i was wondering if i would be able to tell without measuring the exhaust up yet..... i have an apexi n1 3" dp, and i just ordered a ebay 3" catback exhaust....
i have heard that some performance dp's delete the cat/ test pipes space..... so i was wondering if anyone knew anything about the two exhaust parts..... I feel like its a stupid question.
Are they long enough that they delete the cat/ tp, and just fit together from front to back?
basically im asking is the apexi n1 dp long enough that it covers the distance that the cat or test pipe would cover?
sorry for the stupid question.....

Yes, the Apex'i N1 downpipe eliminates the cat along with most aftermarket downpipes.

Generally no, expect to need a test pipe made to put in place of the cat if you're not replacing it.

Edit: Nevermind, my downpipe didn't but I also don't have the same as you.
