C210 Exhaust

[Socrates]

I am going to get a better exhaust for my 1978 C210 Skyline (L24) Fully Stock

I have the following options:

1. Extractors, 2.25" piping to lukey sports muffler to 2.5" turn-down tip - $970 all supplied and fitted at 1 shop

2. Buy extractors from another place ($440), install myself + $60 Engine Gasket = $500 then take to another shop to do 2.25" piping to sports muffler to 2.5" turn-down tip - $430 = $930

3. 2.25" piping to lukey sports muffler to 2.5" turn-down tip straight off existing engine manifold $400

If I choose option two, there is the chance that the manifold bolts could snap as they haven't been touched in 32 years, is the risk worth it?

What would you recommend for me?

I am also going to post in Classic Skylines as well.

sell the car bro

[ahh 33 s2]

for the sake of saving $40 bucks i would take it to the shop, cos the hassel that might provail would be a real pain in the arse,

will the work shop charge u more if the snap the studs any way??

just get the shop to do it then you have piece of mind of warranty and if anything breaks its covered under that quote

Cam ! why the comment of sell it ???

C210's are getting harder and harder to find so keeping them on the road is the right thing to do

There's no way I'm getting rid of this car, mainly for gazza's reason, that I'll never find one the same condition again.

There is another option now added:

Extractors to existing 1.75" pipe, (remove existing resonator) to lukey sports exhaust to 2.5" turn-down tip.

or should i change pipe to 2"?

Check out C210 Exhaust in Classic Skylines for more info.

numbers 1 and 2 are no longer valid.

Revised options are as follows:

1: Extractors,2.25" piping, resonator, lukey sports exhaust, 2.5" turndown tip. = $1120

2. Extractors ($660 installed), existing 1.75" piping, new resonator, muffler(~$250) + 2.5" turndown tip (~$40). = ~$950

3. Existing manifold, existing 1.75" piping, new resonator, muffler(~$250) + 2.5" turndown tip (~$40)= ~$290

That's my options.

I want number 1, but don't want to spend that much so I'm fine with number 2, BUT will it bottleneck at the entrance to 1.75" piping?

Alright i got exhaust done today

extractors, 2inch, resonator (hotdog), flow through muffler. $790 installed

Now my problems:

Extractors leaking and making hissing sound under load + fumes in car. = will take back to shop to get rectified

Heat riser, i was told that my car needs a heat riser, to warm up the fuel in the carby before it gets into the engine so it can burn better.

Exhaust shop can't make a heat riser from the extractors.

I can feel the engine surging when I put my foot all the way down, when it didn't before.

Is this something that can be fixed with a tune or will I have to either rig something to heat the fuel or just put back the old exhaust manifold?

I am planning to get carburettor overhauled and the choke pull of fixed which currently is stuck closed, until the heat opens it (which now i'm worrying about cause there's no heat riser so it's going to take longer to open and it's going to drive like crap for longer)

any help appreciated
