hey everyone i just got an evo and i got about 3k miles and was thinking about putting a catback on it and just wanted to know if i needed to tune it if i just put a catback exhaust on it or will it be fine without a tune ... thanks

 

Catback is fine w/o a tune...but a tune will yield great gains, single best mod you can do.

Yep. I got tuned with exhaust early on and a huge, huge difference. Bigger than anything else I can remember, bolt-on wise.

 

Get a tune!!!!!

 

thanks guys
