[align=left]I am getting my exhaust done soon, and we have talked about this before, just checking to see if anyone has new input. My original plan was to do true daul, no cats, x-pipe, dual flowmaster 40s. Then I found it was better to leave the cats in as the minimal power gain was not worth the milage loss. Now after reading on flowmasters website, it says they do not recommend changing from single pipe to dual before the muffler as these trucks are not made to have that much exhaust flow. Now with that said, I have done improvements and plan on many more, so I am making more power than stock, and it will continue to increase. So should I think about leaving the factory Y pipe then split it back out to the dual mufflers or dual all the way? [/align]

 

I would love to be able to anwser this but as you know i have the same question with my truck.On my last truck ijust went and spent $240 for flowmaster with dual 3 inch tip. I was thinking of doing the same tomy 05 but is this really doing anythingor does it just sound good.

 

I thought you had already done your exhaust? I guess you were just looking then, I can't remember.

 

Yeah i was going to but then i had to pay $1100 when my wifes car broke a valve spring. But its about cooling season here in oklahoma and i should be getting some extra cash soon.So then i can start doing stuff to my truck.

 

That sucks when that **** happens. Always seems to be something when you get ready. Well if we work together we should find the best setup. especially since we have very similar trucks. which diff. gear doyou have?

 

I believe its the 3.73 not sure but thats what comes stock in the z-71s right?

 

I was told when I bought mine the only choices that year were 3.42 and 4.10. I screwed up and got the 3.42 (as I have bitched about before). The 3.73 was in theh catalog, but the dealer said it was not available.

 

I dont know maybei have a 3.42 how would i look to see what i have?

 

You can check your VIN #, then call the dealership and they will tell you what you have. You may be able to find the info on the internet, but I don't know where.

 

Yeah hey on your headers what type did you get. I was looking on performancecenter.com and there are alot of differnet ones to choose from.
