MAC 4-1 Exhuast?? Anyone have these

[ajgs550]

This is related to performance so I thought I would try posting here . . .

I have put in an order for a 4-1 MAC (chrome) system for my '78 GS550. I ordered the header in September. It has been on back order since then!!!! It has been 6 months since my order and every three weeks like clock work they push it back 3 more weeks. I did some digging and found out they send them to Parts Unlimited. I am #5 on the Parts unlimited list to for a header, and the #1 on the list has been on back order since Feb '08!!!!!! I'm wondering if I will ever get my system. Has anyone else out there had trouble with MAC systems?? My initial supplier was Pro Cycle Depot.
Is there anywhere else to buy these systems?? Can we get Marshall in the US??

Any tips would be much appreciated

Get your money back, Mac pipes suck anyway. No performance, sound like ****, cheaply made.

Ditto--being on backorder has saved you from buying crap--get your money back and be thankful

I think you can still get new Vance and Hines sytems for the 550...try dennis kirk..I was going to get a V&H for my 750 before I got a system off of here from a member.
Where in Mpls are ya..I'm down their quite a bit in the spring summer..got relatives and friends down their..I'm up in st cloud.

Motorcycle Pro Shop has the MAC header for $286. http://www.motorcycleproshop.com/det...uct_id=03-0201

I can't speak for the quality of the product. But the shop is a-okay. When I bought my Jardines, they price matched from another listing. Shipped right away. I had my pipes in less than a week.

If the backlog is from the factory, then I guess you'll find the same dilema with these guys. But it's worth a try if you like the MAC.

The MAC setup on my 450 really sounds tinney. I wouldn't buy another. This unit came with the bike.

Thanks for all the input! I don't think the guys at MAC know what they are H#ll they are doing. I do know that the only company to get a new 4-1 system is MAC (that I can find). Vance doesn't make them for the 550. (Only 750 and up) So I think I'm going to hold out a search ebay for a used head header . . .

Has anyone out there used a Marshall Deeptone?? I've seen them on some Brit '70's era 550's.

did you read my reply? i gave you a ebay number that is still on there, if you need it check it out,
or use the mac header,and put a different silencer on it like everyone else does

[ajgs550]

Will an '83 header fit my '78? I know for sure '77-'79 are all the same, but not sure past '79. I'm just worried about frame fit, and access points . . .

[kochic]

even with some work to make it fit, its still a full yosh system for 89$.

Here's the Ebay Yosh full system. Someone should jump on this. I might just to hold onto it until someone needs one. It won't be $89 though. I'd refinish it and sell it for more.

are you guys serious about that yoshimura pipe?? it just doesnt look like it goes well with the 70's era 550's. That and it looks extremely long.

ajgs550, i feel your pain man. Ive been on the look out for a chrome 4-1 for my 77' 550 for the past 2.5 years with zero luck and i really dont want to get a mac or pay 500-600 dollars shipped to import a marshall that to me still doesnt look right and hangs too low. The only 4-1 for these 550's that look good are the vance and hines or an old kerker. These 550's are such good little bikes its a shame they stoped producing pipes for them and all we're left with is the POS MAC!! argh....

Just gotta get lucky i guess... that or get a 750!!

Wouldn't go so far to say MAC exhausts suck, but they lack compared to V&H and other exhausts out there. I've got a MAC, planning on using the header/figuring out a new muffler. A good system if you're limited on budget, otherwise jump on vance and hines.

The midpipe could easily be shortened and most likely the can as well. With as hard as it is to find a real performance pipe for these bikes that is a great deal.
