Hey guys, I just booked my accent in to get a cat back exhaust system installed. I was just curious if anyone has a cat back exhaust system installed and if so, what differences has it made (power(kw), fuel efficiency and sound wise)? Also what size pipes would you recommend? Thanks! :thumbsup:

I don't think anyone has gotten their car dynoed before and after just a cat as that's really not cost effective, but I can say: noticeably less high rpm restriction (anything above 4k was basically unusable before for me), gas mileage may have gone down 1 MPG but otherwise negligible, sounds awesome. Look at my cardomain (audio clip sucks but it has a link to my thread on here with all the steps I went through. Overall was it worth it? Well, it kept me from immediately selling the car, but I dunno that it really helped as much as I'd hoped.

And absolutely no larger than 2.25", unless you want no low end torque.

i had a 2.5" cat back with a magnaflow resonator and a apc dual tip muffler....greatly helped top end ummph and got quite a few compliments on the sound....actually had people stop me in traffic and wave me down to tell me how good it sounded....lol

 

[tunawrx91]

oh okay so 'less high rpm restriction' your saying you had more power when it came to getting the revs over about 4000rpm? I will look at your page and check it out thanks :thumbsup: alright well i think i will stick with a 2inch pipe, its mandrel bent so i wont need to go bigger from creases in the bends. Im excited about the sound as at the moment with just the cannon muffler its pretty non-aggressive. Im doing my exhaust in stages as it is quiet pricey... so hoping to get a highflow cat and then finally headers and forced induction. What would you say was the most noticeable improvement in power from these few option?

I really appreciate the feedback and opinions
I shall let you guys know how the cat back turns out after tomorrow!
cheers

So... bloodninja about the coolant bypass mod, can you explain just quickly what exactly you are changing by doing the mod and how it increases your power so much? Is it a safe mod to do as i dont want to stuff up the engine or anything. And since my car is still under warranty does it void the warranty? Nice page btw! cheers once again

I've done the coolant bypass in the last week as well.
i really cant tell anything, other than my engine performing a bit better.
It Definately cools the engine down alot, from which i was suprised.
Its easily reversible, it takes 5 minutes to put back on, given the proper tools.

 

[tunawrx91]

oh okay cool. so do you think its worth doing or not considering the insignificant changes?

 

[tunawrx91]

i have got my catback exhuast system now installed! =] they put a 2inch system mandrel bent. it has increased the torque and throttle response definately and it sounds a **** of alot more grunty.. so im pretty happy with it. but all i want to do now is more mods haha. anyone think getting a high flow cat is worth while considering its going to cost me about AU$400? cheers

 

[JoeyBello]

Do they even make a catback system? I havent seen any exhaust for this car anywhere.. except the canadian dealer rear section kit.. are you guys all getting custom made exhuasts??

Almost everyone is going custom, it's cheaper than the dealer.

There are some others out there, but not for the hatch.

 

[tunawrx91]

yeah the shop just made a system up for me. most places are pretty reasonably priced too. just ring up a few shops to get some quotes and see how much its going to cost you. best way to go about it.

Just saw the KFX website and they have a catback system for 300$ thats pretty cheap.. does anyone on here have that? Also saw the turbo kit on there... anyone know anything about that or have that as well?

I believe they're still working on the turbo kit to work with megasquirt and until it's ready it seems like not too many people have bitten the bullet. At least none here. Wang's working on a remote turbo set up but he's been unusually silent on it. Damian's got his own turbo set up and it appears to be one of the few completed turbo Accent projects.

Well I don't like that the accent does not have an exhaust tip.. and I dont want to buy a screw on one. Be nice if I could find a bolt on muffler or rear section made for the car. Only one I seen the from the Dealer in Canada and its over 500$ The Kfx pictures look to straight unless its not the actual one for the accent- I wonder if it requires cutting the bumper or what.

Unless it's changed, its either for the 00-06 or the 4-dr. I can't remember the problem, I just remember it doesn't fit the hatch.

Maybe they actually got some legit ones in. Last time I checked, EvoFusion and KFXPerformance both had the same catbacks and neither fit any of the 3G cars. Maybe they got new ones

That's what it was, I knew it was sumpin'.

 

[Sleeper]

It'd be cool if someone could actually buy it again and see if it actually IS compatible with our cars this time...
