How much difference does a header make

[scott-s]

 The engine in question is a 2000 GSX750F Teapot. It's going in an older frame so I'll be running dual K&N pods on '95 GSX-F carbs (and jetting it. I'll be asking advice on that later). I currently have the stock header and a Yoshimura pipe.

 How much difference does an aftermarket head pipe make? And I'm still getting conflicting info on whether the GSX-R header (of similar years) will fit the F bike. I believe something about the oil sump was mentioned? And some of the headers I've seen online don't seem to give access to the oil filter.

 

 I guess what I'm asking is, if I'm not after ultimate horsepower, and mid-range is good for me, is it worth trying to find a good or different header for the Yoshi pipe?

[CockneyRick]

Aftermarket will be lighter, most likely better flow dependent on quality. As for sump, it may be that you will have to get a strainer & sump off a different bike (see my drag bike build thread in projects) also, a few are hard to change filter with headers on, but seeing as you'll change it once in 5k miles, that's no biggy  

And sticking an end can on original headers & mid pipe will do nothing but look good.

 The Yoshimura exhaust comes with the mid pipe. It's not just a slip on. But I needed a muffler anyway and the Yoshi was priced right, so....

[scott-s]

 Other than the weight savings, is there much to be gained performance wise other than on the top end?

 

 I'm transplanting this engine into a GS550,  so I'll be nearly doubling the horsepower anyway. And I like mud range. Just save my money and keep the stock collector?

[CockneyRick]

If you have the Yoshi on, then better flowing headers & a re-jet (then dyno) will help it a lot. Otherwise, it will mostly run the same or worse than a stock can  

[scott-s]

 I'm not running across too many header systems for the '00 GSX-F. I know the 600 and 750 used the same head. I think the Bandit would fit but the collector underneath is way different and I'm not sure where it routes the pipe. Would like to know more about which GSX-R headers might work.

[CockneyRick]

IIRC, the GSXR headers will flow to offside of sump, Bandit down the middle.

Swapping sumps if needed will sort that.

Look at my drag build thread & you can see the issues i had & how i got round it

 Just read that whole thread. You actually helped shed some insight into swingarm and wheel/tire fitment for me. Currently working on getting the GSX750F swingarm into a GS550 frame and converting to dual shocks.

[CockneyRick]

I have done more complex build threads than that. Unfortunately they're on the old site  

[scott-s]

 Getting there (sorry for veering off topic).

 Thoughts on how well this would fit/work with my '00 GSX-F engine/sump?

Those should be alright if your engine has the sump a bit like a triangle in the middle pointing down.

Aren't they for a W/cooled engine? Different spacing so i believe (Don't do water)

He's right you know.

[scott-s]

96-99 was water cooled? I'm still trying to learn about all the running changes....man, this Suzuki interchange stuff can get confusing.

[Captain Chaos]

GSX-R went watercooled from 1992 (750)  or 1993 (1100 and 750 in Murica). Teapot (GSX-F) has always been oilcooled.

To make it more complicated, GSX-R 250, 400, 600 and 1000 have always been watercooled.

them pipes look like aftermarket srad ones. you would need to move #2 and #3 pipes further apart to fit as the cam chain moved from the inside to the offside of the engine  on later w/c engines. spacing would also be different between #1 and#2 and #3 and #4 so need to heat them up to fit proper. but do-able ish.
