I would like to install the LG header system; probably will keep the stock titanium exhaust for for now.... Should I install it with or withouts cats... I live in an area where vehicle inspections are not required..

Is there much of a difference in sound/noise

Any other issues to address??

Thanks.... :z:

Probably slightly quieter with the Random cats but there wont be a gas smell in or behind the car. RT cats, from what I hear and saw at a dyno day, dont cost you any power and actually give you 2-3 rwhp; they are going to cost your wallet though. I used them.

Not fitting catalytic converters to a street-driven car is nothing short of irresponsible, and perhaps even criminal. I don't have them on my car, and it's a darn shame. :eek::

From what I've gathered, I think that you're better off picking one of the following two directions, and going with it:

- Keep the stock exhaust, and lose the cats

- Keep the stock cats, and lost the stock exhaust

I have TPIS long tubes, my stock cats, and the Corsa Ti exhaust. It's pretty loud as it is (although it's not nearly what I would call "too loud" -- but everyone's tollerence is different). I asked here whether or not I should lose the cats, and I was admonished that my car would quickly soud like a NASCAR car.

But, I've also read where plenty of people have ditched their cats, but keep the stock exhaust (or at least the stock headers), and they don't find their cars to be too loud.

So, my advice would be to consider keep EITHER the stock exhaust OR the cats stock if you're going ditch one of them.

It's kind of hard to vote for no cats after that statement.

If you drive many miles a year (more than 2,000) I agree 100%

If drive less than that that, I only agree 99% :z:

iv'e heard my exact same setup but with cats. night and day difference. the hp difference will probably be negligable either way. plus they're like $500 cheaper. you've got to go no cats. flames rock

Cats=dead weight...loose them.. :D
"Lose" has to be the most misspelled word on the Internet. That, and "bumper." (And it's a good thing there's spell check on this site, or I would have spelled "misspelled" wrong!) :lol:

I live in an area where inspections are required but then again I live in an area where you don't bring a knife to a gun fight so WTH. I lost the cats and kept the Glock for safe keeping. I love the smell of the race fuel so I could care less for my car IMO. As posted by others if you're going to modify one lose the other and just change it all if you can afford it. Good Luck! :cheers:

I bought the FLP system that provides easy access to swap cats in and out for emission testing. I run with cats off most of the time. The smell is no where near as bad as when I first started w/o cats 2 years ago. You get a slight occasional wiff every now and then but thats a beautiful thing :D
