custom, stainless exhaust??

[GS750]

I have been offered to have a set of custom made pipes (for free) by my local school.

All they need is my old set (luckily I have a spare set too) and they will replicate the bends etc and will even make a custom muffler which they will replicate the flow from my tranzac.

Thing is that the teacher said he really would like them to tig weld the pipes onto the 4-1 collector.
Is this a good idea or would it cause some other problems??

I currently have the older trazac pipes and a generic muffler fitted up to the bike but as I have only ever had full stainless on cars I was just wondering if anyone has had experience with full stainless on the GS's??

does it inprove performance??

I would not have them weld the whole exhaust toghther.It's hard enough to get header pipes on without the muffler hanging on the back.

There's no performance gain from stainless

Unless lighter material is used because stainless can be stronger than mild. And then the performance gains would probably be very small.

If they're going to "do you a favor" as an educational experience, have them do it correctly.

A 4-1 collector is fine...most of us with aftermarket exhausts run 4-1 setups.

The best thing they can do for you, though, is make separate exhaust manifolds.

Look here to see what I mean:

Random statement of the day award!

Stainless is more about longevity than performance. If it would hold up to the heat you could make it out of wood.

Spoke to the guys today and they said that they would be able to do the 4-2-1 system instead of the 4-1 The issue is that I dont really want to have them stacked like yours, plus which pipes are best to combine at the first collectors?? Should it be 1&4 and 2&3??

I wouldn't go for a 4-2-1 personally. You want your primaries to be as long as possible and there's not enough room to get a proper arrangement going. It would look interesting, though...if you go that route then yes, the ` and 4 and the 2 and 3 need to be the shared combos.
