X force or Invidia N1
 

So I'm not sure what to pick. It's between these two. Which sounds better? The 3" x force or the N1? The x force is $100 cheaper but I don't really care.. Thanks everyone.

I have had my N1 for about a month now.

Impressions.

Its the N1 Catback but with the catless front pipe as well so keep that in mind it is louder with the front pipe.

Its quite loud, probably not street legal.
Tone is nice and deep
Idle is very nice
Up through the gears is nice
Slight boxer burble
It is very slightly droney @ 100/110kph, enough to be noticeable but not enough to need to raise voices for conversations. It doesn't bother me.

The only real downside i have found is, on downshifts from say 3rd down to 2nd on the brakes it is droney.

It makes no disguise of the fact its loud which i knew going into it.

Its still a nice deep sound though which i do like.

Its a daily driver for me doing about 500km a week and i'm not sick of it yet so it can't be too bad :P

edit : combined with a hks drop in filter and the weight loss from the stock system, it defiantly pulls harder up top, probably around 5-7hp gain.

Thanks for your response, how much quieter do you think it will be without the front pipe?

Also, where did you buy it all from?

ft86 speedfactory here on this forum.

A decent bit quieter, but its still one of the louder cat-backs on the market.

Would be street legal as a catback only i would say, but that's purely subjective.

A straight through catless front pipe does make a big big difference.

Cool. So if I was to buy the front pipe from the US it would fit RHD cars?

my catless invidia one fit just fine, bolted straight up.

Some of the combo over/front pipes might have troubles but they usually say so if they don't fit RHD

Ahh I can't wait to get my car! Got any videos of you driving with the exhaust on?

Front pipes are identical in both LHD and RHD so you'll be fine.
