Fast Intentions exhaust

chalmene · 10-24-2019, 08:19 PM

Has anyone installed the FI catback alone and thrown a code? I understand a tune is needed to get the most performance, but can this exhaust be installed and operated without the need for an immediate tune?

Mine didn’t & I had test pipes from them as well...drove nearly 1,000mi & got tune because I wanted the extra ponies

Thank you for the feedback! What was your experience, was there much of a performance improvement before the tune? After the tune? Also, stock intake or aftermarket?

Typically people get a tune after doing intake, TP/HFC and exhaust.

Had Z1’s aftermarket intake & was noticeable difference with mods...baseline was 270, 290 after exhaust & intakes...then 309 after tune.
7A/T tuning in 4th gear (1.41:1) so lower #’s than stick shift Z.
Tune felt very noticeable

Installing our Cat-Back exhaust system (alone) will not trigger a CEL. Do you have any other modifications installed on your car?

If a CEL was triggered, I'd recommend scanning the code to confirm what it is related to.

Is is possible that you have any exhaust leak or something else was damaged / removed during the installation process?

Hey Kevin, I don't have the exhaust yet, but plan to order soon hopefully. I don't have any other performance mods currently, was only asking in general if I should expect to need a tune immediately after. Will most likely install in conjunction with some resonated test pipes.

You won't need a tune. I ran mine on 2 different cars with over 120k miles total. You are good to go. Even with an intake, you are good to go but it would be better with a tune. Do Highflow cats or test pipes, you will need a tune for sure.

A tune is not required when installing our exhaust system and test pipes.

There is a small chance that test pipes can trigger a CEL. If it does, the only way to turn off the CEL is with ECU tuning.
