i currently have a zzp midlength combo sitting at my house but for some reason have a bad feeling about it. im thinking about selling the combo and just getting a new 2.5 downpipe.

my question is how big is the collector/exit of the stock manifold. i have an 07 so i guess its the same as an ss/sc. if it really small i might as well put the headers on.

thanks

anything is better than the stock manifold, even if it is the same as the ss/sc. its really restrictive. put on the header. do it..... now. if not, gimmie the header and i'll use it. its the one i want but no $ until after september.

 

More info on the ZZP combo please.

I have a GMPP manifold and a ZZP dp I would trade you for your setup if your interested.

Let me know.

 

The Exit or collector on a stock manifold is 2 1/4"
I have one sitting in my storage and have measured it many times.

 

^^^^^ what he said. if you still thinking but selling i'd drive out to make a deal.

 

its a mild steel painted header that i touched up and put a few coats on of new paint. vht 2000*flameproof. idk how it will hold up but its on. its not baked yet tho. 1.5 primaries 3"collector. 2.5 inch catless mild steel dp bolt in on both ends.

 

If only it had a CAT as I have to pass emmissions.

 

you can always have one welded in lol.

i still havent made up my mind yet. but i probably will end up selling it
