Catless Downpipes no tune?

adamconti · 05-21-2017, 09:56 AM

Before you get mad at me understand i am tunning the car!!!!

kk, so plan is bring the car Tuesday to get the DPs installed then bring it home and tunning. just want to ask/make sure it's safe to drive it home with the catless pipes and no tune? i'd assume it'll cause a CEL and me to run rich?

ALSO, plan to tune with the MHD Flasher any advice on that is appreciated!! going to have the car on a charger (2 or 6 amps, i'd assume 6 is best?) as well as turning off as much as possible inside cabin.

thanks all,

A short drive will be ok.
Why don't you just flash MHD while at the shop. You can plug in your charger there. If anything crazily bad happens, they might be able to help you on the spot.

closed loop fueling you'll be fine.

you'll get a cel after a few drives but just ignore it. I drove for a few weeks with catless downpipes and stock tune. If you drive for long enough on the freeway the cel will actually go away lol.

you're best off with a tune. it will run and perform better.

Read the post STR8-SIX, he's just driving home from the shop, then he's going to flash it.

LMAO! Dipshit gets banned but the stupid is strong in this one.

Antetokounmpo · 05-24-2017, 03:12 PM

Since this question has never been asked before, I'd probably take it to the dealership and have them do it, just to be sure.

Tiago@VRSF · 05-24-2017, 03:29 PM

No problem with installing downpipes without a tune

mike@x-ph.com · 05-25-2017, 12:12 AM

You can drive the car as much as you want and as aggressive as you want even without the tune. Its 100% safe

Brandon818 · 05-25-2017, 12:45 PM

I drove my car without a tune for 2 months, I had a cel, because the car knows its letting emissions out the back , but its 100 percent safe.

Harambe my dear sir - I did read the post. I was simply saying that he is still best off with a tune (ASAP)

please do not go into a circle jerk with LMB and start appreciating each others posts after he insults me.

Lol, that's amusing coming from the guy who's on his third name this week and settles on "molestor". Oh, and smart guy, that's spelled "molester".

Yeah, you can drive the car with no tune. The car has safety parameters set in place. Obviously WOT is highly discouraged.

Haha the mods must hate this guy or something. I don't even think he posted anything that could be considered ban-able. Maybe his username
