Hi i recently purchased evo x gsr

current mods:
Aem Intake
ETS UICP
TSUDO Ver. 2 Catback

im planning on puttin on an ams widemouth downpipe and tsudo res. Test pipe

I have one question will it be safe to run those with out a tune??

Thanks

 

We ran all of our bolt on upgrades with no tuning for around 6 months with no check engine lights and the car made amazing power. We offer a pretty nice downpipe as well

Thanks!

What Mike said.

And you'll should be safe, but if you're **** about it, then get it tuned, but then again, it'll be a waste of money just to get tuned on a widemouth, unless all those other mods you have currently on your car haven't been tuned on, so if you got a tune after the wide mouth + the current mods, then i'll ve well worth it.

 

How are you liking the Tsudo exhaust? I was planning on getting it but then decieded to get the Agency power exhaust instead.

 

thanks guys for the information...and btw the tsudo exhaust is great and the fitment is perfect!

 

welcome
