Alright heres my situation I just recently bought a y-pipe from warpspeed and it didnt fit perfectly. I thought no problem so we made it fit and I used the gaskets that they provide because my others were desinergrated. Now ever since I have installed it, theres a terrible leak coming from it.
1. Do you guys think I should also Install some Nissan gaskets just to try and see if it works?
Also Im going to be replacing the rest of the exhaust probaly with a catco high flow cat which at either end has 3.5 outlets/inlets. Now if i get a Warpspeed b pipe for the rest should i get a 3.32 or 3.5 size diameter pipe. If i get to small it wont fit and there will be a leak.
1. Should I get it with the resonator or not?
Lastly I want to get a Magnaflow Mirror Finish Street Series muffler either model number 14830 or 14833 because its a dual pipe like my stock one.
Now I would of just got a greddy catback but laws in Maine have recently changed so we cant have any aftermarket exhausts that dont look or sound like stock version. The greddy wouldnt let me get it inspected in Maine. Now with the choices I have now it will look stock but give me the performance I need. Anyhelp will be very much obliged. I need some suggestions with this stuff guys... Give input dont just read it...I need some input fast because i need this all done by January.

 

I don't know about your y pipe but if you get a magnaflow muffler it may look stock but it doesn't sounds stock. Mine sounds like a V8 instead of a can of bees. If you want stock then go with the %gen max's exhaust. It looks good and I think there is a growl when you step on it.
