Who's Really Interested In A 3" 4th Gen Catback?????
its heat shield lol I could care less what it looks like it had to be moved back to install the resonator
its a smaller resonator than stock and its far from random thrown together. Thats the resonator I wanted because I have heard it before and know what the sound is. I dont like surprises. some of us dont have the $ to go out and get a custom 3in done
honestly at 5-600, its not a bad price. i made my own a few years back buying a 30" long resonator, 2 "J" mandrel bent pieces, a 5 foot straight, and a Dynamax muffler, all in stainless steel. cost was a little under 500. and labor was free (obvsly). just my 2 cents. and pic for reference::


Id ont know if you guys have had your car on a rack and looked, but theres a spot right after the resonator where it has to be crushed to fit. Didnt get a picture of it but there is no way in hell a 3" is fitting through that spot when a 2.25" had to be crushed. Or be prepared for some rattle. When I was getting a high flow cat and resonator installed today I noticed this and theres no way around it
Dude just to re-post mine and the Wizard's. It works. Trust us lol.
Well... This is exactly what the white car sounds like.... It ain't bad.... I still prefer the exhaust note w/ mah OBX's on (COMING SOON), but I can see why people like this sound.
ugh ill go take a picture and show you what im talking about. Theres a support bracket thats its crushed to fit above. I dont see that in your pictures so its obviously removed to fit the 3in pipiing. If its a pointless bracket then I suppose it can be removed. gimme a min and we will compare
Ah yes, the useless bracket.
Yes the useless bracket is useless, you will need to remove it to fit ANY aftermarket catback, none of my cars have it.
See if you worded your post right, we wouldn't be busy pwning you now. Learn how to use words better, we'll be more friendly.

Here are a few pictures of my 3rd Gen tubing kit and catback!






3" for you or a 2.5"? I may get one too since my 2.5" on this Newly acquired 4th gen is crush bent and the muffler selection wasn't of my taste....I'm thinking about experimenting with some HeartThrob Exhaust components since he does use T409 SS and has some straigh thru muffler with no drone! The Magnaflow setup on my 3rd is awesome and the components I used is completely drone free....thnks to that 18" resonator and that gigantic 5" x 11" x 22" rear muffler!!!!

Interested in this. So a 3" kit is $175, including all hardware, clamps, etc. ready to install? Quick question to. How loud would the car be with a 3" exhaust with no resonator? What are our options with resonators?
Yea Headers will come down the road too. Are you doing the headers for our specific model or going with the Altima ones? I havent decided quite yet. Ive always heard, and was even told by my exhaust people, that the stock 4th gen headers arent super restrictive as far as air flow. No sharp bends or anything. Obviously the aftermarket ones will sound better but as far as performance Im still wondering if its worth it because I didnt put my exhaust on for sound lol

Full details in my dyno thread if you care to notice, but the cattman 3" isn't responsible for 13whp/20wtq alone

You might need to slap your exhaust people.

lol well that doesn't prove that the stock headers are restrictive that just proves how the aftermarket headers are better designed. Im not arguing that the stock are good im just saying they arent as bad as they could be. Thats a nice curve BTW, no real noticable dips nice and smooth like the stock curve and yea ive seen the thread very informative
Glad to see the list finally picking up. Im in for a 3" when its ready! 
I know ebay shorties are basically refined stock headers.
My whole idea is keeping the shorties and goin 3" ypipe (equal length hopefully) to 3" exhaust. I know the longtube headers have a 2.25 or 2.5 y-pipe but have better top end gains. I guess what Im wondering is would the shorties benefit from a 3" y-pipe? If so would that improve more low to mid range, or would the 3" y give me more top end?
Just trying to see how much power I can get out of the shorties before going OBX. Sorry if im goin a little off topic tho, lets get this list filled!

Andd a 3" y pipe that caught my attention in another thread. http://www.ebay.com/itm/OBX-Downpipe...ht_1539wt_1185

EDIT: Ive never seen that OBX downpipe, has anyone had experience with that? Im wondering how the front would bolt on it looks too short

That's what that 90* elbow is in the auction picture is for, so you can use it whether you have fed or cali spec.

Sorry I didn't fully answer your question did I ???? Your options for resonator are nearly endless....You can use Magnaflow 4" round mufflers, Magnaflow glasspacks, Hearthrob, Cherrybomb, Summit glasspacks, Jeg's, you can use what ever you like this is a tubing kit!
so is this for the 3" cattman catback or the brm? and last time i talked to bryan he had told me he goes off of the backorders, so ten people on a list isnt going to cut it, they need to actually order it as well

out of all the exhuast setups i have seen on here that has to be the most ghetto rigged job i have seen. i had a silly exhuast for a while and it didnt look THAT bad.
