Reading is not your best skill. The person selling that exhaust wants to get a motordyne, which is different then trying to get a quieter exhaust like you. 99.999% if the people selling their FI exhaust are either selling their cars or want to change to a louder exhaust.

Ah, Ron White is correct

I agree, but there is no need to insult yourself. I am pretty sure you are not stupid .

Sorry for the confusion guys, I wasn’t saying the rasp was from the FI exhaust, I know the hiss is from the Art Pipes only lol. I may go with the entire setup like someone mentioned if that really does get rid of any rasp!

Thanks for the feedback guys, I did my research before buying the FI CBE a couple of years ago and was just curious if there was anything new and better on the market! I know FI was in the process of making new muffler tips that are supposed to be 20% louder so maybe I’ll just get that whenever it’s for sale.

Good to know most people don’t switch from FI, makes me even more certain I made the right choice.

I have the exact same setup as Rusty. F.I. LTH and 12” res CBE. I feel like it is ok, until I get to the track and there it seems quiet compared to many other vehicles. I was wondering what a single exit titanium setup like Tomei might sound like, keeping the same long tube headers. It would help with adding a real rear diffuser too.
Or not, as I just realized Tomei has issues with the Velox diffuser too.

You don't want it too loud. Because it might get you kicked off of the track.

I began my order and cancelled it. I'm with tomei now and I'm so happy I didn't go with FI. they are way too quiet.

depends on the setup.


my FI is just as loud as Tomei if not louder just with a better tone. Tomei is too high pitched/ricey for my taste. thats why i stuck with FI, just personal choice.

Agreed! I am going to straight pipe mines so I can attach a rear diffuser. I'm guessing she is gonna a sing like the fat lady at the opera!

I tell every Z guy with turbos that straight pipe is the way to go. the turbos are basically mufflers already so why add more? lol plus, you cant go wrong with any combo of FI products.

makes me excited to go 4" straight pipe on the GT-R :stirthepot:
