I have a 2010, been in the shop 9 times for emissions. I live in Calif. Any advise is welcome.

 

Delete it and never look back!

 

What about my smog cert evey two years?

 

Throw the stuff back on smog then re-delete. A few hours of time every couple of years is worth it in my mind

 

Just how loud is it, once all the deletes are done? My 04 was strait piped all mandrel 4" and pretty loud. I liked it but 8 years of it and I'm enjoying the factory '12 right now. However, that exhaust brake seems like it should sound pretty good rolling into town with 10k behind it. I'm understanding..can someone tell me what something sounds like..might be quite a question.

 

No louder than a stock truck
