No, I wasnt like complaining about the downpipe being 2.5 at the start, just no one said it was lol, I like Buschur style a little more, 2.5 for like 3 inches, then expands to 3inch. But whatever. I still dont think the inner diameter of the Apexi is 3", esp where it meets the DP, the welds look like 1 smaller peice was welded on right where the resonator is. But I love the way the exhaust looks and I do like the way it sounds, I just wish it was a tid bit louder. My 2.5inch custom with Thermal Muffler was louder.turbo90awd said:TALONTED TURBO,
How long have you had your N1? Mine was really quiet when I first got it and nowadays its quite loud.
Yes it has resonators, but it would sound stupid without them. It has such a nice rumble at idle.
As far a full 3" exhaust goes, unless your O2 housing has a 3" inner diam. why would you need to switch to 3" right at the O2? By keeping the diam. of the exhuast at 2.5" until you pass the flex section, you will keep the exhaust gasses at a constant velocity while they are still hot. Once they get to the "cat back" section of piping they have cooled considerably and a larger pipe may be used without sacraficing velocity.
I thought it was 3 inch too, but I converted the metric numbers off rre's site and 2.75 (70mm) expanding to 3.35 (85mm) is what it comes too for the N1 catback. I'd rather you be right though.......PokeyTheDSM said:Uh, no, I measured the pipe myself when I swapped my exhaust for my stock downpipe, and it's 3" inner diameter, unless I got some "Special" Edition, which I higly doubt.
