I've just bought an FTO and have never done any mods to a car before.

What is that tank thing that lies parallel to the bumper and connects to my dual tip exhaust? Is that a muffler?

I asked a place on getting a new muffler and they said my car can only get new intake piping and a tip on the end. They said a cannon style muffler wont fit. Is this true? Obviously not, since marke's fto has a rather large muffler.

How much do they cost?
Thanks alot.

Yes that is your muffler. A cannon type muffler will fit. I have one on my car (in fact I have an N1 muffler, which is much fatter and larger in general than a cannon).

Talk to Cypher Industries in Myaree, Genie Exhausts or other people along those lines. What is your budget? Cypher (who did mine) did my entire system from the Cat back for $900. If you went for a cheaper non N1 muffler you could probably cut that down to $750 or so.

From someone who has never modified a car either. What does a bigger muffler do for the car? Louder noise, more power? Embarassed

Well, when you increase the diameter of your exhaust piping you get a better flow of air (more air can flow), except if you go too big a diameter where you start getting too little backpressure and the performance of the engine will decrease.

Mufflers are designed to muffle the sound of the engine to make it quieter, and in doing so, they restrict exhaust gas flow. Most mufflers on normal road cars (not performance road cars) will even have 180 degree bends in the piping inside the muffler.

A replacement performance muffler always has a straight through design so the gas takes no bends, and the diameter of the piping through the middle of the muffler has a larger diameter also. Due to this though, the mufflers are louder (ie they muffle less), which is what gives your nice sound, and generally more power Smile

It's a finger-in-the-wind guess as to whether or not you'll actually get more power out of your FTO, though! Smile

We dyno'd Mark's car and mine back-to-back - his with sports exhaust and stuff, mine stock - and the torque curves were exactly the same shape from 3000rpm to 7800rpm - and within 2 lb/ft torque across the board.

Near as dammit to identical, "all else being equal". Which, of course, they never are in real life!!

But it'll sound nice...............

As far as I'm concerned, the FTO isn't really a car you can get double-digit percentage power increases from by playing with induction, exhaust, etc. But that doesn't mean you shouldn't jump in there and give it a go if you'll enjoy yourself doing it! Smile

i got a cat back full stainless steel exhaust from a nakaya tune FTO

open to offers if anyone interested

and it sounds great

So if i were to replace my muffler, would that "tank/muffler" near the rear bumper simply be swapped with a better muffler? Or would it be relocated so that i get less bends and more flow?

If i just wanted SOUND, and no performance gains, how would this be achieved?

Well it all depends on what type of muffler you went with. Any performance muffler from a performance workshop will give you a decent sound, and the type of muffler you get, whether its a back box replacing the stock FTO one, or a cannon/N1 type that points out of the rear of the car will really depend on how how you want the muffler to look.

I went with the style I got because I liked having a big stainless steel muffler on the back of the car.

One more question,
When you get a cannon styled muffler, eg N-1, does the old muffler get removed? I'm sure i've seen cars with the orginal muffler near the rear end of the car along with an aftermarket cannon muffler out the end.

Yes the old muffler gets removed. What you have probably seen is a resonator, which is a length of tuned piping designed to reduce the drone within the cabin of the car. I will take a picture of the underside of my car sometime in the next few days to point out out the different parts of my exhaust system as an aftermarket system.

Maybe someone can take some pictures of a stock system for me so I can point out the differences?
