Muffler delete

Does anyone know what would happen if I were to remove my mufflers? I know it would sound louder but what are the pros and cons?

Pros, you would see a small HP gain and get a super loud and deep exhaust note. Cons, if you live in the city or in a quiet town you will most likely get messed with by the cops. Some places you get lucky and the cops will tolerate it, other places they write tickets.

Just noticed you live in Cali also, most places in Cali you will fail the SMOG visual testing without mufflers, you need some form of muffler and cannot exceed 93 decibels, or you will fail.

If u do muffler deletes u will lose back pressure and end up actually losing HP while gaining a super loud aggressive exhaust tone. Get a Axlebacks that gives u the tone u want while being street legal and keeping the back pressure I would recommend any of the three types of Borla's or Roush ones. I personally have BBK Full length headers and xpipe with high flow cats, GT resonators and Roush Axlebacks an my car is better sounding than most V8's with after markets exhausts

I think deletes sound terrible. It's too raspy. But my personal preference is more of a deep subdued note.

I pulled my cats off for a day and would agree with this 100%. The exhaust note sounds MEAN while you are still and it sounds pretty good (still very very loud) when you accelerate slowly the second you give it some gas you get that dreaded rasp and ping sound. I would stick with axel back's as suggested, the magniflows are popular as are the roush ones. Im sure it depends on where you live but I can get a Roush axel back installed at my dealer for $600 or $700 with a lifetime warranty. If your in Cali where you need to meet emissions, axel back is your best bet for sure.

Thanks guys for the info. I've decided to get some magnaflows instead. I don't want to lose hp or get that rasp noise.
