Ok for your 6A10, its a 1.6 engine, and its a V6. So basically, your extractor should look like 6-2-1 if its gonna end up with one single muffler. Nowadays most v6 goes with 6-2, with twin mufflers and a crossover pipe between the two outgoing pipes, which looks kinda like a H.

Before you do up your exhaust system, first decide what you want. What kind of driving style do you want? High rev, power coming in the top RPM range, or normal driving, maximizing torque delivery on the lower RPM range? Do you like to hear exhaust noise, or you want the noise to be kept to a minimum? All these questions will affect your final decision.

triple post...

I'm going to get a middle box soon. How much did the person charge you?

but after removing it, what are the downsides to it? increased FC and noise?

One question to you - what's a 1-4-2-3 extractor? I've only heard of 4-2-1 and 4-1.

If you do not have a turbo, then there's no point putting in a mis-firing system. If I were you i would spend that extra money (and the money saved from NOT destroying your exhaust system every month) on actual performance upgrades. But since you asked, there're a few ways to do it - an ECU upgrade or get this gadget called flame dragon.

I'm sorry, I read his post after I posted my first post. That explains the two posts.

Neway, its not called "mis-firing" effect, the correct term is "anti-lag". But that only happens on a turbo engine, so fitting an anti-lag mechanism on a NA engine seems pretty redundant, and in my perspective a completely foolish action. There are a few ways to achieve the "misfiring" effect - the easiest way is to run the car rich, screw up the ignition timing and voila - instant misfiring effects as well as significant loss of power and increase in FC. One alternative way is to use a flame thrower device like the flamedragon, which you can easily purchase and fitted in any accessory shop that sell's em. That's my two cents on it.

You mean mandrel-bent pipes. Mandrel is a tooling process that when applied to bending pipes, allows the bent sections to retain the same diameter as the straight sections (when normal bending processes reduces the diameter or create folds or other obstructions that might impede the flow of gasses). Its the most preferred method to create manifolds for use in race applications, if my memory is right.

Err I think you've misunderstood the meaning of mandrel bent pipes haha. The design of the pipes has nothing to do with whether its mandrel bent or not... mandrel is just a technique to bend the pipes, just like port and polish has nothing to do with designing an engine head. The design of the pipes is up to individual tuners, for specific usages. I think the one you see is a mandrel-bent pipe that is shaped in a way so that the exhaust pulses will optimumly scavenge the next exhaust pulses at a certain RPM range, meaning tuned extractor in short. And I also know some turbo manifolds are formed like that (we call it banana manifold) haha.

EDIT:

I think you should call it - mandrel-bent AND tuned extractor.

I can only answer one thing with confidence - there's no way an exhaust mod gonna affect your rpm/speed ratio. Means, no matter what you mod, you're still gonna rev the same amount of rpm to reach a certain speed. Speed per rpm is determined by gearing, not engine power. So a good exhaust mod will give you more power, or smoother power delivery, but never any affect on the rpm or speed.

Any car can change to open pod air filter without replacing anything except the OEM airbox and perhaps the ram pipe.

cat back exhaust means moving the cat all the way to the end of the exhaust pipes - which is also known as a straight-out setup or whatever you wish to call it. If you look underneath the car, you'll only see a straight pipe connecting from the exhaust manifold all the way to the muffler. That's a cat-back setup. No cats, mid boxes or bullets in the middle.
