Installed my zzp DP today, got a leak at the gasket that connects to the resonator, so im going down to Napa in a bit to get a new one and try that one lol :p
anyways my exhaust was dead with that stupid clogged cat, it now sounds pretty beast!! haha oh how i missed it. i think it actually sounds louder than when i first installed that Magnaflow DP could it have been bad from the get go?
oh and i'll be getting an Overkill tune soon as well, finally lol

here's the pics of the two...
that flex piece looks pretty restrictive on the magnaflow one lol



the ZZP one has a much Bigger inlet



and the old cat



this came out the other side

 

Good deal Frank, good to hear replacing the cat solved your problem. Before getting a tune though I think I'd figure out and fix whatever is causing excessive fuel to make its way into the cat. Otherwise that ZZP downpipe is going to look like the Magnaflow one before you know it.

 

thanks mike, i know why though. back when my crank position sensor was bad i ran the car like that. it would shut off on me a bunch of times, then i would try to start it and kept trying and trying but it wouldnt turn on of course and all i would smell is gas

 

So can anyone help me? i installed the other gasket and i still have a leak its really bothering me lol its making a sort of ticking noise where the leak is :p its just not sealing right, is there anything else i can try?

 

Chibi, I'm driving to your house for a tune.

 

LOL let me get my software first.

Frank, the only thing I can think of is putting a little black RTV with the gasket?

 

black rtv is gasket sealant, i'm sure it will be fine with the heat.

 

will it withstand the heat? if that doesnt work, im just going to get it welded lol

idk why it wont seal right though

 

ok cool
i'll probably try that tomorrow, could that small leak be causing the ticking noise? im kinda worried about that

 

Hi `Frank, I know it has to be frustrating 4-Sure..

Is the thread good ? Does the bolt tighten all the way ?
It's possible that you have 2 bad gaskets...I've purchased a part & it was bad & took it bad and the 2nd one was bad also...Wish you good luck on resolving this problem & I know that you won't give up... Does your auto parts store only show one gasket for your connection ?

Like Mod `Mike posted, they do have some amazing sealants for heat out there, but I understand that may not be a permanent solution (?)
I was going to post ~>WELD that sucker on (LOL), but really I would not ~> GOOD LUCK 4-Sure
