local muffler place will straight pipe my truck for $60......just wondering if there will be any downsides to doing this..........will my mpg go up or down?

 

I did my 06', though I didn't see any change in mileage, I did get the attention of a few more people. All I can say is be prepared for LOUD

 

Other than a slight drone @ 1500rpm, I wouldn't have mine any other way. Stock is just plain too quiet. This thing isn't that loud at all unless you are really getting on it. You "it's too loud" guys are too old

 

will they be installing one section of straight pipe or 2 ?

 

just taking out the muffler and putting in a straight piece of 4" in its place.

they kinda made it sound like it wouldn't be much louder, but then they said "those trucks need to breathe"

i just dont want to loose any mpg.

 

Hey I'm only 31 and my '06 is LOUD, I love it, but it is LOUD, just ask my neighbors.

 

You won't loose MPG just by removing the muffler (you MIGHT gain a fraction) but you just might loose some due to the fact that it is so hard NOT to put your right foot down.

 

Trust me you will lose mpg, only because you won't be able to keep your foot off of the pedal. I did mine and love it. EGTs are lower and the turbo will spool up faster, but I have learned to set the cruise and just let them go by. If you can stay off the throttle, it does seem to help. As for noise i was afraid of that myself. I basically live in my truck. I am a communications tech. and it is nothing for me to drive 4 hours just to change a cord. Most of the time the cruise is set at 78 and I have no problems or complaints about noise while on the phone. Overall I am happy.

will running a straight pipe fail the truck when it comes to emmissions for inspection? i live in texas.

 

I straight pipe my 05 with kitty, best bang for buck sounds great.

 

As far as I know, no. Especially in Texas. Maybe in Cali, but who wants to live there

 

on my 06 cut out muff put a 4" T in and went to 5" stacks I left the kitty and man this thing sounds great when at 60 or above sounds no louder than my old gasser with flowmasters,but when you go above 2000 rpm they hear you comming and boy do they look ,some frown, but most give the thumbs up.BTW Im 43 and love the sound .

 

I'm thinking about doing mine......

 

Mine sounds good, no drone driving unloaded. LOUD with heavy trailer going up hill. BTW no smog/inspection at all for diesel pickups in CA.

 

i have a straight all the way with the bullydog 5in 45* bend tip and when i hit 2000rpm it sounds like a gasser with straights. it has that loud poppin or rattling noise for about 5 seconds when i hit 2000. does anybody elses do this?
