so im lookin at exhaust kits and it doesnt say anything about including any catts in the turbo back kits. does that mean it uses the stock catt??
---AutoMerged DoublePost--- how does it sound in the cab, like how she barks but it seems like its loud in the cab... is it? ---AutoMerged DoublePost--- and also if you delete the catts and straight pipe it would it pass emissions in NY, bc i know a gass truck wont pass, but im still dont know much about diesel testing normal driving it aint too bad at all, them lbz's and llys are quiter for some reason:humm: |

Yeah, if they test in NY and you remove the cat, it's probably a guarantee you'll fail...
|
damn, so is it a big sound diff if u leave the catts in??
|
No, it's not that bad. My truck has no cat, but it's got the stock muffler, and it sounds virutally the same. The muffler by far makes the most difference.
---AutoMerged DoublePost--- Just get a good muffler, or no muffler, and you'll be fine. If they do emissions testing you'll have to keep the cat, but I'm not sure if there's a restriction on mufflers... |
im thinking of 5 but may go with 4 not sure i have a stock truck and if i decide to go insane with it then go 5inch
|
4 inch is good for 500+hp and its less expensive
with a 5 inch you gain a few hp less then the 4inch with a stock turbo |
so you think 4 inch is the way to go now?
|
i have a 4" down 5" tip mbrp exhaust on my powerstroke and my friends say they here me a 1/2 mile away and i have a cat.:dixie::dixie:
|
good i think thats what ill do for cost reasons also:c:
