I cant really compare, I did not have the FI full system just the X pipe sections, with TP's though it was pretty loud, nice, but resonably loud.

Ok thanks. I placed the order we will see what happens. Hopefully with the invidia exhaust there is little to no hiss and I hope it sounds good.

Daishi, are you unhappy with your FI Catback? I would imagine it is pretty loud with the long tube headers.

Really? I have the 12" with stock cats, and the hiss is pretty noticable when I let off in low RPMs...but I do not mind it one bit. I even kinda like it; makes the car sound raw :tup: Tell us how you like the new exhaust compared to the F.I. Oh, and I will also be getting the FI RTPs installed too, so I'm assuming the hiss will get even louder?

Sure u will be good man, like before I ran my IGCBE with Cheapo test pipes that rasped on the stocker , nice rumble when going to full INV.

Be simular to my videos I would guess

It's loud but not too bad.the hiss is loud and annoying and it sounds like the hiss comes directly from the xpipe. Makes thr car sound cheap and broken.

Gotcha. I'm running stock cats and manifold, and there is a very slight hiss. I'm sure the headers exaggerate it.

In for your impressions of the new system vs. the FI CBE with your setup.:tup:

Exhaust has been installed and has reduced the hissing to basically nothing. Exhaust has little to no drone in the cabin.

so you are happy with the setup now...:tup:

Yup, dont get me wrong the fast intentions exhaust is a great setup, very free flowing sounds great but personaly i didnt like the hissing the exhaust made with the long tube headers setup. With a HFC setup or stock cats im sure it sounds great and you wouldnt even notice it but catless with headers I wasnt a fan.

So basically now you are running with LTH and invidia exhaust? if im wrong, correct me:tup:

Thats correct.

Nice man


Installed...whew

nice exhaust, I am ruuning ART pipes with this cant notice the hiss

Overall Invida + motordyne ART pipes are less louder then my previous FI with 18"resonator.
