what kind of crack is mac smoking

[timebombprod]

ordered a 4-1 exhaust from mac 2 nights ago, said a week shipping, got it overnight, i am not complaining about that at all. was reading up on this exhaust and it is advertised as a 1 piece exhaust, so no welds right?(im not mad just wtf) first the headers and exhaust tip are two seperate pieces, which is normal its just a slip on and tighten down piece, the exhaust has a welded in baffle so i know thats not the 1 piece part, so im guessing its the headers, each header is welded in place. now maybe they welded over where it goes from the 4 to 1 part, but like what the heck mac first you dont wanna answer my calls and put me on voicemail, not automatically but somebody is doing it (different amounts of rings) but now u gonna advertise this as a 1 piece system and the things is like 6 different pieces welded together.

i am not mad about the exhaust, its a performance part and its what i bought, but how is the advertisement correct by any means? and what the heck is with putting me on voicemail i just have 1 question.

if im wrong about this then what does 1 piece exactly mean, that the headers are all one piece when you buy it?

edit: and some of these welds look like poop.

Ya'll are just talking different languages. They are talking 1 piece "header" is the four down pipes & the collector, 5 parts, after being welded together, becomes 1 part. If they advertised 1 piece exhaust system, it was probably a misprint from the secretary, doing the add. Some come with 4 separate down pipes & you need to slide them up in the collector. Actually comes with 5 separate parts. The rear part is the muffler, some co. probably has, but I've never seen, a 1 piece 4 into 1 complete system, that came with the muffler already welded to the header. As far as the phone calls, welcome to the real world!! Just be happy when that doesn't happen.

MAC exhaust are probably the lowest quality of the pipes on the market and priced accordingly.Their customer service is probably the same.
They are still probably alive because they still make exhaust for ''rare'' bike.

MAC stand for Make Another Choice.

Do not overtorque the flange at the head and make sure you have new gaskets.

It's been said many times here...I have said it too....DON'T BUY A MAC SYSTEM!!!

[timebombprod]

i already bought it bois. if i dont like it ill prob go back to stock or save up for the v&h. i wish there was more to choose from

[timebombprod]

just forgot there isnt a v&h being sold for my bike new so id have to find a used one with the baffle still in lol. im fine with the mac i got it for $100 less than the v&h and i didn't want stock because i want some noise

i have the cv carb tuning link thats the pink background so ill be learning to fine tune them when i can, if it runs fine with how its gonna be set up now then theres other things i could do for my bike first.

Not a lot of choices, when dealing with some of these old bikes. You've got to do what you've got to do. For what you've got, I'd not fool with the jetting till you know you need to. My opinion, stock jetting with the MAC pipe will be fine, as long as all else is stock. Stock air system, no mods.

just one up on the mains the baffle is 1 1/2 inches long measuring from one side to another on the circle. ill put it back to stock if it ends up working better.

I bought a MAC for one of my old Kat 1100s once, mostly because it was cheap as hell and I wanted the dual exhaust look for the bike. It felt flimsy and sounded a bit hollow but for the money, it fit well and it did its job as advertised.

Yep, MAC is the only choice available for a lot of bikes.

Yep, MAC is the only choice available for a lot of bikes.

And it's FAR from cheap for my bike, combine that with their reputation and I'll live with ugly pipes!

There was someone on this forum a few years ago who was in the process of reproducing the Bassani header for the 1100EZ with plans of other models after that. Anyone know what ever happened to him or what the outcome was?

I wanted to buy one but just lost track of the thread, life got in the way.
