Heya, just installed it yesterday! It is in fact from the cat back. So no worries about the O2 sensor and such. It sounds GREAT! Thank you for your help and guidance!

Only problem is, well.. I thought I had a lot of people that wanted to race before.. Now I have people weaving through traffic to catch up to me so they can challenge me! XD on roads that clearly have cops EVERYWHERE! Lol I'm like "do you think I'm stupid?" Silly mustangs, save it for more empty roads xD I have too easy of a license plate to try do that on a busy road =P

But thanks again! I'll have pics and video soon!

you can get a catless down pipe and you wont need a tune just get a cel simulater what that does is it spaces the rear o2 sensor so you wont get a cel and it will just run a little richer but thats ok, shared_pm me if you have any questions i used to work for subaru, dont listen to 75% of people pn the forums they dont know shit half the time just my .02 cents

 

Don't forget to about boost creep/spike from being untuned it's not just about the cel

 

I don't plan on doing anything more than this. Its catback and haven't had any problems yet. I just wanted a nice sound and to replace the stock one which was rattling.

 

Turbo-back is where a tune is necessary... and dont listen to "just doing the o2 sensor trick".... that may work on 350Z's... but not on turbo cars.... and I told you it would sound AMAZING!

 

yeah, I love it! thanks again. But yeah, the only problem is that now that that's all done, it's time to sell her.. I have to. The next college I'm getting into would require me to leave the car, and I can't get any loan to cover what I owe. =/

 

lol that sucks! Where you going?

 

Just buy a WRX muffler for 50$. Slap it on. Use the rest to pay your higher insurance premium.
