Hello to all,
I am a new diesel owner and not sure why it took soo long! 2009 Silverado and looking to just deepen the sound a little bit. What are my options on exhaust systems? Cat back going to give me a throatier sound or do I need to do a full system? Keeping the factory warranty is a must for now, so please keep that in mind...

I look forward to all of your expert advice and thank you in advance.

Ty

4'' straightpipe will make is sound much better... i recommend MBRB. 5'' will have a deeper sound and many say they are glad they got the 5''. it will lower your egts and improve mileage... idk what to say about CAT back or TB. I would get a TB though. you could always keep the stock exhuast and put in back on if you had to go to the stealership...

if you do tb and get ride of you DPF youll need a programmer to hold codes. which your dealship might not like either. But i can say my brother has an 08 cat back MBRP duals and it doesnt add to much sound

If I put on the full system and programmer, I can always unplug the programmer and set back to stock before service correct? How does a programmer work? Exhaust really shouldn't void a warranty. My last Hummer I had an aftermarket exhaust and the dealer never said a word. Diesel engines different when it comes to aftermarket?

I hate not knowing anything about this. Sorry guys there will be a lot of question, considering I want to do this right the first time.

well a 300 quad will do it. But it leaves a ghost well is shows that you have flashed it. but i dunno if you would have troubles just dont program more power to it. only use it to hold code from dpf off. and you should be ok
