fast intention exhaust help
 

I want to keep my stock cats. which one would sounds better with a deep tone , no farting noise ?

non resonator , 12 inch or 18 inch ?

I had 18 inch res and now have non res. I love the non res. there's no "fart noise", don't worry. It's just more volume. Find some clips on YouTube. There are clips of both setups. Some from people here on the forum.

the non res would sound nice with stock cats ?

Haha...fart noise. I had that problem but now I keep the car away from Taco Bell...well, the car and driver. >.>

Best sound I have ever heard, tone and volume, are high flow cats with non-res. Second: stock cats with non-res. Not obnoxiously loud.

stock cats with no res still improves performance and has a better sound than stock right ?

Better sound is relative but it will give you a HP bump. Find a group in your local area, someone local is sure to have a set of F.I. pipes. Also, search youtube.

Can't find a good non-res with stock. Sorry.

i think I'm going to go with the non resonator or just 12 inch resonator. the first video has stock cats right, that sounds pretty dam good

If you are concerned about the volume go 12". All those are stock cats...I think.

stillen gen 3 cold air intake + fast intention 12 inch cat back exhaust = YAY OR NAY ?

Gen 3s are good intakes. I don't see why you wouldn't.

Stock cats with the non res version sounds freaking awesome. A high quality exhaust like FI compared to stock, there isn't even a comparison. It's like driving a completely different car.

Also I was kinda concerned about volume at first because I had never had a car with an aftermarket exhaust, but after a few months of riding around with the 18 inch res I found myself craving more volume because this exhaust makes such an amazing sound. So I got a non res'd x pipe and swapped out my 18 inch res x pipe.

Guys thank you I will be getting the non res exhaust. Only reason I'm keeping my stock cats is cause nissan told me to keep my stock cats so I won't void my warranty

Someone please correct me if I'm wrong, but I don't believe hi-flow cats or test pipes automatically legally void an auto warranty. Any aftermarket part has the possibility of voiding your warranty if the part in question directly causes a malfunction. The dealership can refuse to cover the repair under warranty since it was not a stock manufacturer part. Even though test pipes are not road legal (at least here), I don't think that legally voids a warranty for say your clutch, headlights, etc. Like I said, someone feel free to correct me if I'm wrong.

How much louder would test-pipes make an 18" resonated FI exhaust?

Got my gen 3 first then my non res cf FI exhaust with stock cats. IMHO, most amazing sound. Just loud enough and it sounds absolutely amazing. Zero regrets! I almost always drive with the windows down just to hear the exhaust. I have a few videos on YouTube with a GoPro mounted right on the bumper above the exhaust if you want to get an idea. (RoyaltyB)

IMO skip the 12 inch res and go non res with the stock cats.

thank you man, I'm deff getting the non res cbe , i might also go along with the carbon fiber. i will deff check out your videos

cabin noise , will i still be able to listen to music comfortably ?

After installing my FI, my aftermarket audio has become a waste of money.

Exhaust note > Music.

How much louder is the FI with 18" resonators compared to the stock NISMO exhaust?

good video for non res, stock cats...

I have the FI w/ 12" resonators and FI LTH on my 09 nismo and it is night and day from stock. Like a different car almost...HR engine on steroids. The volume is not headache-inducing nor is the exhaust note super different from stock, just really enhances the growl like the pipes are up to a megaphone. There is the typical hiss/buzz at cruising and lower rpm and a lot of cabin drone. But imPo there is no better full exhaust. If you're on the fence I say definitely go for FI!!!! Full disclosure, I didn't personally install it but the previous owner did (and babied her - thank you ryanboy) which is why I bought her. I'm in love and from what I can tell all other FI customers are very happy as well.
