that is the question.... i want to add an exhaust and noticed bullydog offers a 4 and 5" turbo back system.... is bigger always better ?? should i go with the 5" ?? any1 have it that has an opinion ?? thanks guys,scott

 

just putting it back up top

 

The only reason I can see in investing in a 5" system is if you are over like 900hp. 4" is plenty good up to 700 or so hp. 5" may give you a deeper, throatier sound than 4" though.

 

the sound would be a plus but i really dont see going over 700 hp ......geez what would that cost me 4 grand ?? lol <br><br>later guys,scott<br>

 

$3300 or so for tranny, $1500 for at least a B-1 or HX55, $1500 for a set of Bully Dog Step 8 injectors. But then you may need twins instead of the B-1, that's about $4000.<br><br>Gets real expensive real quick.

 

ouch :'( :'( :'(

 

I just put a five inch system on my truck. I don't have anywhere close to 900 hp but I wish I did. I went to a local truck parts store and bought all the pieces and made it myself. It does have a very good sound. After about a month though I had to put a muffler on it. It was not to loud but the five inch pipe will resonate pretty bad and starts to rattle everything on the truck. I know that the five inch was over kill for my truck but I like it and it does sound good. Maybe somday I will have 900 HP ;D

 

DieselCrazy,<br>Just some food for thought.........<br>Chrysler replaced it's 3&quot; system this year with a hybrid 3.5/4&quot; system to upgrade hp from 245 to 305. The bean counters don't spend money lightly...................<br><br>Do some research because there are formulas that size exhaust by cubic inch and horsepower. Can you find a formula for 4&quot; single exhaust that supports 700hp, turbocharged?? <br><br>Good luck and it doesn't hurt to question the folks that are happy with what they have, Larry

 

Most guys only run 4&quot; exhaust and they are close to that. 4&quot; is plenty big enough. But like the old saying, &quot;Bigger is better.&quot; ;D
