I'm about to the a muffler deleted but will this make my car weaker and make me loose gas mileage? And will it make my car value go down?!
Please and thank you

Driving value will go down. If you want to sell it, keep it and put it back on.

keep the stock exhaust remove the 2nd cats and the resonator you would get a little growl and it would sound better than deleting the muffler

So I have my resonator deleted already,
How much is it to deleted the 2nd cat?

Is there any downfall getting the 2nd cat deleted?
Like, passing smog, or anything?

I'm sorry really noob with this, really want a sorta g35, 370z sound but without spending a lot.

Got my resonator deleted, and it's not bad, little more growl should be perfect!

It's illegal in all 50 states to remove a working catalytic converter, so yes this will fail smog anyplace they notice it.

I would suggest to just get an exhaust. It would be easier to swap out instead of welding pipes back together

+1 for new exhaust. If you have enough money get good one but if you don't get cheap one.
The cheapest one is around $300 shipped

Yup this is a good option ^

Also be careful when chopping off pipes because there is a chance that you will get some rasp. When I deleted my resonator I had rasp in the higher RPM range which was not pleasing.

Thank you sooo much guys! This help a lot!
