2016 370z
Tomei test pipes, y-pipe and muffler
Z1 cold air intake. Planning on getting it tune at intec racing in Kent. Can I drive it till then, check engine light is on. Haven't scan yet....

With those mods, you’ll be good to drive there then tune. The CEL is most likely from the test pipes.

Figure I ask, even if it's a stupid questions that's been ask over and over. I email intec racing seeing if they have any available openings to get the car tune. Should I be worry and not drive it? Oh btw it's loud ASF..

Better safe than sorry so I don’t blame ya for asking. But you’ll be fine. When you said muffler, does that mean it’s deleted? If so, paired with test pipes it’ll be loud. Do you have the o2 spacer in?

Should be OK as long as you baby it a little bit until you get the tune. Watch your temps in case you're running lean. I would definitely see which DTC(s) are causing the CEL (probably the test pipes messing with O2s but it only takes a minute to check).

Hey thanks for replying Panda!
Full tomei; tomei test pipes, tomei y pipe, tomei muffler. No o2 extender spacer, figure I get it tune. It's loud ASF cruising at 80mph even with the volume at half turn. Just waiting on intec racing to get back at me with available openings, so I can get it tune.

Will do, thanks!

Hey guys, it's better just ask this silly question then to learn it the hard way. Just got my Z 4 months ago. Installed a catback and that's it. Planning on getting a resonated test pipe. Will I NEED a tune for the TP? I don't want to tune the car since power isn't my focus at the moment.

Better yet, learn how to search. This question has been asked and answered many times already.

If you don't like the site's search function, go to just about any web search engine and add "site:the370z.com" to your search string.

After I had an Invidia Gemini fitted to mine it wasn't running as sweetly as it was. In the end I tried disconnecting the + terminal on the battery for a few minutes to see if that would reset the learning and force it to relearn.

It worked far better than I had hoped and it's been sweet ever since. The only downside is having to reset the clock and the windows. If you do it read the book for the windows because you would never figure it out otherwise.
