Hi there,

I am incontact via email with my upgrade and tuning facility. They have also suggested removing the Catalytic converter.

Any comments?

I hope that shop gets shut down. Cats are put into cars for a reason. I'm not qualified to give advice regarding performance benefits of this mod, but seriously, the last thing we need is more pollution. Imagine if we all removed our cats.

I quote "These cat are a blockages in the system we get a better airflow" This is what he said.

He says that with the Dastek UNI Q CHip I can get between 5% and 8& more power.

I don't know about Forte but when I remove my cat on my 99 cougar it need a MILS eliminator on the O2 sensor in order to prevent engine code!
And yes it give some HP and better flow...........and kill some more birds!!!

Best case scenario: A 12hp increase. Big deal. Not worth the harm you're doing to the environment. If you want better performance, do it the right way.

you can replace it with high flow cat instead. removing it completely would also make you forte illegal to drive anywhere. I'm sure Canada has the same laws as the states, if so, you would never be able to register your car again. Because you would never pass emissions. I agree with above, the extra hp isn't enough to remove and make your car an illegal street machine. cats nowadays do have better flow than in the past and you can replace it with a high flow performance cat and still get a good gain.

Most provinces do not have emissions testing, so you could get away with it for a while...

As a 'performance guy' I understand your desire for more power, but as a person who likes 'air I can breathe' I will ask you to please consider any other options. There are plenty of ways to make a few horses more (especially 12... that's like, *nothing*) without wilful destruction.

If your shop is suggesting this, avoid them like the plague from now on... what else are they going to suggest that will do more damage than good? Besides, the cats Kia uses are a passthrough grid design, they are as high flow as possible, while being built to last. You can see right through them... how is that restrictive?

Yes...I agree with you guys. I was just wondering. Thing is I am looking for ways to increase performance and fuel economy without doing hectic stuff like a turbu etc that will void my service plan and waranty.

I have found someone who can remap the chip, undetectable, and that is a good idea. So I am just scratching around for some more ideas.

Hey guys,

Sorry for only checking in now. Been a hectic week. And for the record, I dont have my KOUP yet, first checking things out. I always do a lot of homework before I buy certain things, and a car is one of them : ) For instance, I will send the dealer a spread sheet to complete, listing things like CV replacement prices, wheel bearings, clutch etc : )

But things are looking like I will own one soon. Anyway, have a look at this site. Remember I am in South Africa.

Um...not sure if I can post the URL for it? You guys got any other 'not too hectic' ideas for increasing performance. On my list so far is the chip remapping and a K&N filter.

Can I post the link to the company's website? Well the guy simply told me they will re map the chip, instead off using a piggy back chip. This will cost R9990.00 and will give me a 12KW and 40NM gain, taking the KOUP to 127KW and 234NM.

I think this is not bad. He garuntees me that they will not pick it up and I requested a copy off the original mapping. He says that when using the piggy back units, the dealerships can pick it up as the unit throws up a certain fault code when the dealership plugs in. But now I don't understand how the dealer wont SEE the chip has been remapped when they plug in...???

Please advise!

9990.00R is 1300$USD (or can). That's not cheap for about 20HP!!!

just about the original post.. taking out the cat..

yes it's illegal in some / most places to run catless. that being said modern cars with cat or not still put out less emissions the cars from 10 years ago with cats.

that being said.. i'd recommend a high flow or a spiral wound cat, the performance difference between catless and those will be 2 hp or so. and they'll make your car have a better sound.. generally catless dp's tend to bring out a BLAT in the exhaust note

Yep, this sounds like a waste of $ to HP with the remap. Put a good intake and exhaust first then work out from there. You might consider this and the RRM lightweight pulley as a cheaper alternative to the remap.

Make no serious remaps before 7500mi so you can break it in and see the results above. My car seems to keep getting stronger as it goes...loosening up a bit.

tuning the forte's looks like it'll do great for numbers .. because your air fuel ratios are in the shitter lol from the few dyno's i've seen the AFR's have been where you should be for a boosted car, retuning it up a few points (from 11.3 up to 13.0 like a normal NA setuP) would result in some good HP .. but it's not worth spending 1300 bux on when you could buy stuff to turbo your car for all that lol

There's not really any need to remove your cat, older catalytic converters were a lot less efficient than the cats nowadays, I just got a cat back exhaust installed (2.5" piping to a magnaflow oval single chamber muffler) and I considered buying a high flow cat to free up some more of the power that is lost through the crappy exhaust system now, but it really wont make that much of a difference, IMO. I'm loving it now as is, stock cat and all. and the K&N makes a big audible improvement and it seems like it helps a bit performance wise as well, just so you know

well with most cars now a days it's mostly how the DP is formed, usually it's got a crushed section and 1 or 2 cats also the dp's are usually underside in newer cars the DP is usually the most restrictive part of the exhaust as well as the header
