those of you who have a megan racing dp for gst's..

i recently purchased a megan racing dp, with 2.5''inlet and 3'' outlet but after looking at my catback, i'm not sure if it will fit. I'm not the original owner so i don't know what kind it is since it doesnt have a name on it but there is a reducer looking coupler about 2-3inches long between the catback and the cat.
Is this the piece that apexi n1 exhausts come with? (do apexi n1s have the name engraved on the tip or anything?) if so, will the megan racing dp probably be too short? thanks

the megan dp will go all the way to the end of where the cat is now. So if your current exhaust attaches to the cat then you will be fine.

Sure does.. i have the apexi n-1 on my 1g. it should have a little plate on the bottom of the muffler tip that says apexi.

If you don't have one your might have fallen off I don't have one on my 2g and its a real apex n1

hmm..if it is an n1, will the megan fit to the reducer coupler?

YES. The megan dp for our cars necks down a bit to meet up with the stock cat and it is a cat depleted downpipe ( that just means its longer). As long as you have the reducer that comes with the N1 catback system you will be fine. gasket sizing might be your issue. i have a megan dp mated to a PIT 3" cat back. I welded in a straight 3" pipe elimating the neck down on the dp and the reducer that came with my catback at the same time. I used the flange from the reducer(the 3" side) welded it to the 3" pipe to bolt it to the catback......str8 3" from the flex to the muffler.

Thats a smart idea^^^^b/c from what I understand, there would end up being a neck down at the catback and the downpipe, so it would be a full 3" exhaust with a 2.5" small neck in the middle of it...Definitely not going to help the flow much...So, you could do with that guy did and just use a 3" pipe to go in between the downpipe and catback so there is no restriction

Just a Quick Q tho:

If you got the 3" downpipe and the 3" Catback both from MR, would there still be a bottle-neck or would both units have 3" outlets and matching gaskets between the 2 pipes...??
