Z-story exhaust on a stock 240

A convertible would make a great pond-liner though.....

You're right but I may have to wait for the snow to melt. And you are making me feel like a "DeZart'er" even though The first engine swap I ever did was a 283 into a 56 wagon.
I actually prefer to drive the Z.

Oh, you're hot today although I've been "Sean" of humour recently - it'll grow back !

Sean,

What is the functional difference between your race-sport and street-sport headers? would the race-sport headers be too much for a relatively stock L24 with 40DCOE's (eventually i will likely get the head ported and probably a cam but not for some time).

I like the idea and look of the equal length headers such as your race-sport model

[Sean Dezart]

There is a bandied-about myth that the ONLY header to have, the 'ultimate' is an equal-length version. This emanated (imho) from flat-out racing designs as these headers are designed/tuned to give the maximum hp possible at a very narrow and therefore specific engine rev range.

None of us in our Zs run all the time at high revs and neither do we run at the same revs - what all of us need is to maximise low-down torque that we use for every gear-shift and the Race-Sport is better for that. But the milder (or even stock) the engine, the smaller the difference between the Street-Sport and Race-Sport....so little that it's not 'worth' paying the extra but the more you prepare your engine, the more relevant to fit the Race-Sport header because you'll better exploit that engine or, said another way - return the investment.

Effectively the Race and Street-Sport will follow your current set-up....the 'wilder' you go, the more adapted will be the Race-Sport.

Thx Sean for another great explanation

You take better photos than I do  !

 

I'll try and load some video clips sent in by customers....there are more on Facebook that I can't seem to pull off.

Today was the day I got around to install the Z-story exhaust'. Looks good so far. Haven't started the engine yet as the system is temporarily fitted and I still have to install the updated R200 drive shaft. Goal is to finish tonight and run on the dyno tomorrow. More photos to come.

Finished the install and made it to Club Dyno Day

I've only recently came across Z Story on FB.  Thank you for the video and information.  Sounds fantastic.

Hiya and thanks.

Dave R reccomedns my headers, the version depending upon the engine spec and drivers' needs.

Kind regards,

Sean
