I need to put a new exhaust system on my truck. 03' / air dog 150 / K & N filter / 60 hp reman. injectors / fuel chip / What recommendations would anyone have. How much can I open up this exhaust system without causing problems with sensors and other issues?...

 

Our '07 has the cat deleted and an Aero 4040 muffler, sounds awesome, no issues. Lately tho, I've been considering putting a quieter muffler on, just in case the greenies or popo decides to take offense to it. I love the sound, but ya never know....

Just make sure you are going to be happy with a loud exhaust if you decide to go that route.

 

i have 5" turbo back to 6"stacks no cat or muff never had a problem till about a month ago got a $100 dollar ticket for being to loud so i put a Hush Power from Flow Master it sounds great and they clame it adds power

 

diamond eyes are a very nice kit that fit like a dream. i have done 5 of them and they have all fit good. They are cheaper as well and come with a muffler and a muffler delete kit.

 

Love my MBRP on my 03 sounds great

 

MBRP, Diamond Eye and Expandit are all great exhaust kits. Let me know if we can help.

I just run a 4' straight pipe. The girl sounds pretty good, i always get complimants. I never had any issues with the smokeys, but in my county you dont have emissions, so maybe thats why, i dont know. Plus its really not that loud untill you really step on it.

 

ordered 5 in turboback expandit straight pipe from Diesel Dawgs(thanks Luke, I'll be back) on friday... was sittin on my doorstep monday mornin, put it on in about 30 min sounds awesome wouldnt have it any other way. On the interstate cant even hear it in the cab, granted mud grapplers have alot of road noise

 

I run the 4" non-straight piped to an RBP (*Rolling Big Power) 5" pipe, sounds pretty great...with basically just an Airaid intake. Not too loud, not too quiet in the cab

 

me peasonally i am running a stock exhaust except for i have a 4" glss pck that is put on backwards to a 5" tip sounds good and its completly legal cuz i still have a muffler there but who said it had to be functioning just my 2cents spend them how you like
