Today I went and checked on my engine swap. After checking the front exhaust manifold, I noticed the precat is gone. If it broke up, would there be any pieces of it remaning inside the housing? I just cant see someone hollowing it out. It looks like 2 cylinders were blowing oil instead of 1. Would it be alright to re-use this manifold now? Or should I go with headers?

 

headers

 

the only thing about headers is that i may replace the clutch also and im gonna be out more than i wanted to on this thing

 

Go with headers.

 

Headers

 

the obx headers are only 350, so i dunno what to tell ya. i wasnt even gonna get headers, but after hearing about precat failures, and knowing i was gonna keep the car for a long time, i bit the bullet and got them. the 30+HP aint that bad either

 

Well after doing some research, im gonna be a scrooge and wait on the headers, its xmas time and i really want to get my lil one a dirtbike, so I am just gonna hollow out the other side and clean them up real good. My main concern is that this engine Im having installed, I havent heard it run yet.

 

great time for headers

 

Another VQ dead

Bump so people read this and gut the cats or get headers.

This is exactly what happened to my old car. Front cats fell apart, ruined the cylinder walls and then clogged up the main cat. Check your main cat. I bet you'll love what you find.

 

you could alway go with custom maxima headers 180.00 plus shiping get the slits flaw fixed for 40 bucks and call it a day. a few poeple on here have them and thier alternative to getting rid of pre catt cheap .

 

anybody had OBX headers installed recently I need to price them asap and a HFC cause I have a good feeling my main cat is running for its life

 

Ebay is your friend:

For a HFC go with either the cattman fastcat, or just run a testpipe instead.

No disrespect I know where to find it I just wanted a couple people who have OBX headers to tell me how much they spent for labor sorry I wasnt clear at first

 

Yeah I would get headers if I was you especially not in a strict state on emissions. Looking to get some sometime next year Cattman probably or OBX not sure yet.
