Confusion

Is this safe to do?, being this is my daily driver car. Will I get a CEL in the future if I decide to delete one of the cats? and is it worth it? Will it free up alot of HP?

no horsepower gain or check engine light, but you do get a nice little growl out of it when you WOT cheap but satisfying mod

edit: heres an old clip when i had the stock exhaust with both resonators and one cat deleted http://www.dailymotion.com/video/x8x...aust-clip_auto

I have no cats or resonators on my na-t 3'' turbo-back, still has a nice smooth sound, and not too loud at all. No CEL, should free up some power, but not enough to mention or feel.

if it's just one of the cats likely no CEL will pop up. If it does come on, it will have no effect on performance.

Confusion

well I'm n/a, if I decide to delete a cat, which one should I delete? and will upgrading to 2.5 help? and I want a nice growl but not too loud, so I don't know whether to delete my mufflers or resonators, I saw a couple clips on youtube and I like the sound with mufflers deleted

sound of mufflers deleted will be LOUD

I would just delete your stock resonators and put some Magnaflow mufflers on or something if you are going for just noise. You aren't going to get much performance out of deleting just a cat or other select parts off the exhaust on these cars. Even if you replace the whole exhaust from the headers back to the mufflers on an NA car with our SCs, you aren't going to see much power gained. If you want serious good sounding power/sound, boost your car!!!! But if you want just a little rumble compared to stock, do what I did, which is what I said above. Delete stock resonators and put on Magnaflows or some other kind of mufflers. My car has a nice deep/low rumble to it. Not too loud at all.

Confusion

Thank you!, well if a full complete exhaust will just get 9 hp, I ain't gonna go through it, maybe I'll just go for sound then

My brother deleted the resonator first and that gave a nice purr..

Yeah that's what I would do. It sounds good man, get some Magnaflow mufflers or Tanabe axlebacks on there without the stock resonators and it WILL sound good. Trust me, everyone says my ***** sounds good lol. It's just that I've asked the same question a million times on here and everyone has always told me you won't get much power or any for that matter without turboing these cars. But it is true though, it's just I don't have the money to boost my car... yet.

Confusion

okay thanks for all the feedback guys, maybe just some new axlebacks and deleted resonators is the route Im gonna go
