What power gains with 4 into 1?

Because it cruises smoother in top gear. The stock 750 twin has so much low end torque you can easily cruise 30 mph in 5th gear which is 2000 RPM.

Thanks for that Bountyhunter. Mine came wiith a totally rotted out stock 2 into 2 and the crossover was basically not there so I've only rode it with the aftermarket MAC 2 into 1 that I installed. Even still it feels like it could pull a Honda Civic out of a ditch.

One of the best articles on headers of all time !!!!!! Have the mag somewhere but I'll be damned if I can find it and I thank you for putting it on here !!

Very interesting article. I am really surprised how poorly the Yosh pipe performed.

That always has surprised and stuck with me too ....... I remembered that the Kerker won out and that Yosh lost and (RC my pick was middle of the road) but wasn't sure enough to post it so I went looking for the mag and could not find it. Didn't want to comment on that without proof so I kept quiet. Maybe it needed jetting changes or removing the baffle to work but running around without a baffle is something I'd never do. (Well ok maybe a few times). :lol:

I had duel crossover tuned exhaust. After the wreck I ordered a set of Jardine slip on's to replace my old and damaged ones. The owner of the shop where I was working got the side draft instead because they were half the price. HD guy. I hated them but put them on and quit the shop. Crook. I lived with them until I could get some new ones. They jumped in price so I bought the V/H system I have now for a little more money. I wanted to see how much power gain I would get. I was disappointed. Not much if any. I bought two extra baffles, Competition and Drag. The drag is too loud and the top end fell off. the competition has smooth power all the way up and the street was like I put a cork in it.

I am also running the MAC 2-1 now. Runs good, but definitely feels softer under 3k RPM. Pretty close to stock performance otherwise, but I think not having the crossover and dual outputs hurts the low end.
