Dual fto exhaust question

Pato · Post by **Pato** » Sat Jan 28, 2006 4:06 pm

Hey guys just got a question about dual exhausts. Ive got all the basic mods covered, ie ARC intake, RPW extractors, Unichip, heavy duty clutch, and a 2.5" catback, but it goes into a big chamber at the rear and then has Dual pipes comming out of each end of the big chamber, to the tips, so its got two, twin tips, ( sorry bout that explanation but i hope you understand... its similar to the mr2 exhaust). the cars exhaust is really quiet, and i think that big chamber thing is restrictive. I want to keep the dual exhaust look, but was thinking of having the exhaust split into dual pipes earlier and have to straight through pipes to twin cannons, thus eliminating the big chamber thing. has neone done this???

Also has neone gone for a big bore highflow cat? how restrictive are the stock cats??
Cheers

You mean like this?? Although most of the exhausting work is done by the time it gets to the muffler, a more direct route for the air to take is always better.

This is a more efficient design for a twin setup.

Also keep in mind the muffler type. There are 2 main varieties, the baffle type (quieter type) which is more resticitive. Similar to this stock muffler:

Where as a straight thru type is again better for flow. As you can see the gases can pass thru without restriction. These make more noise than the baffle types.

And contrary to popular belief, the noise you exhaust make is also proporational to your tip size and type. With all the good exhaust components in place, a larger tip will sound louder then a smaller one. An extremely large tip... you'll look like a tosser.

And yes, stock cats are not the best for flow... depending on what you spend, you can real good ones that have great flow. But they get pretty pricey towards the top end on the range. I paid about 400 for mine - which was getting towards the better types, yet they showed me one that was worth 1800

Hey Bennoz,

Firstly, I assume that is the underside of your car. Question. What did you have to do to create the second cut out for the exhaust. With a standard bumper, there is only one cut out. Yours looks finished off quite nicely.

That doesn't look like an FTO

If so it's not a stock rear bar, or even one thats been modded... to clean.

Is that Y design made for an FTO ??

Again it was for an MR2, and that I know of there is no off the shelf design like that for the FTO. But welding pipes & mufflers together is not hard. You present that pic to a good exhaust shop & they could make one up pretty easy.

Pato, have a look at this thread

I posted some pics of my exhaust, not the best quality I'm afraid but its difficult to get good shots without ramps.

Hey Kaz have you had any trouble keeping the car at a legal ride height with that setup? Did you have to do any mods to the fuel tank to set that up or has the FTO got enough room past the fuel tank?

I have never had any problems with the ride height, but keep in mind my car hasnt been lowered yet. To answer your questions about the fuel tank etc, I dont know, these pipes were on the car when I bought it. Look if I can get my car on a hoist or get hold of some ramps I'll take proper pics from all angles to help anyone out who may be thinking of doing this setup. Let me see what I can do

i dont see the FTO exhaust as being restrictive, as a gain is seen in aftermarket exhaust its not huge. The FTO is 2000CC and runs a 2.5inch exhaust, cars double that capacity run 2.5 inches.

So going to the rule of thumb the FTO exhaust is not restrictive and if you want it louder, maybe go a different muffler setup at the back. You'll be suprised how much louder a cheap muffler will sound to an expensive one.
