Used exhaust questions (Fast Intentions)

louiey370z · 05-04-2015, 06:12 PM

I don't know jack sh*t about exhaust setups, or how to identify them, so I would like to ask you guys. I found this from a seller and i might buy them

Fast Intentions high flow cats and axel back mufflers (no mid pipe)

Now my questions are:

How loud will these be?

How much HP gain will these be?

How much would you pay for them?

The high flow cats are FI, but the are not part of the exhaust. It's a separate item.

The other part is not FI. It is not the full exhaust. I think they are called short tails (made by several manufactures) and are meant to replace the muffler section of the stock exhaust. I think the combination of short tails and FI HFC would make for a pretty loud set up.

FI exhaust is a cat-back exhaust (everything from cats back). It should include a mid-pipe (with various size resonators), muffler cans and the tips.

I recommend you do some research in the exhaust section.

So with the pics above, I assume they'd still be pretty loud when installed? How much would you pay for the items in above?

$0. I would not run a loud exhaust.

If you were wanting to run a loud exhaust, how much would you pay for them?

You should check FI site for the price of those cats brand new and verify how many miles are on them then make the decision of what u feel comfortable paying. I would get short tails brand new. And like cooltoy said that's going to be really loud.

They have less than 1200 miles on them. Also, will they be obnoxious/trashy loud, or aggressive and deep loud?

They'll be loud for sure. You're removing the muffler section. HP gains? Not sure there is even any from the short tails.

You'll prob gain 5-10hp from those high flow cats.

By loud, what definition? Trash/fart loud, or aggressive/deep loud?

I just asked the guy and he said its quote on quote "stupid deep without the HFC and once those are on it sounds so amazing you will thank me once you buy it"

The videos didn't sound super deep lol...

No they didn't sound super deep. They sounded super sh:tty. I agree with looking into a cat back exhaust. The guy sais your gonna love it,but is trying to sell it after 1200 miles?

cooltoy · 05-04-2015, 07:27 PM

Just remove your stock muffler, if you want to get an approximate idea of how it will sound.

cooltoy · 05-04-2015, 07:33 PM

My guess, and I am not an expert, that it would probably sound something similar to these.
