so i went to my local exhaust shop and we put my 04 v6 up on the lift and i told him that i want my y pipe cut right after the cat's and then a set of duals fabd up with flowmaster 40's and he said that was a bad idea because i prob. wouldnt pass inspection/emmisions with a cut y pipe, and i would lose alot of my low end torque/hp. so he said my best option was to have them put on a single flowmaster 40 right after the y pipe so it would have single in dual out and let them fab up dual pipes, he said that is my best option for sound and power, is it???
if i buy the muffler and tailpipes online he said to assemble it all = $250 labor
if i let them do every thing muffler/piping/chrome tips = $475
Despite what he said, I would go with your original plan of cutting the pipes after the cat and running true duals straight back. The prices seem about right (depending on where you live that is).

yea im going to go to a couple more places and see what they tell me. that was just the second place i been. the first was crazy he wanted 500 in labor alone because he said it would take him a day and a half to do a true dual set up
thanks for all the advice im going in in a few hours to get it done iv decided to just pay the 475 and have them do the single in dual out super 40 and all the piping
hey man get another quote because if you really think thats kinda high. A general price for them to do it all should be around 250 ish. Not 475, id check with all the other local shops.

it shouldnt take a day and a half lmfao! i know how muffler shops work and the work it takes to fab a true dual.. my cousin owns one
i would just go with your original idea. tell him to shove it if he tells you its gonna take a day and a half to bend two pipes to connect the cats to the muffler and weld
i found my GT take offs on cragslist and got them for 40 bucks. mufflers and tailpipes im sure you could find gt take offs for cheap, and pick up those knock off flowmasters cus they sound the same, and then all the shop has to do is put it up, and bend two pipes and weld
my shop only wanted 120 to install the whole thing and connect the mufflers to the cats
Like TurtleSlow I got my GT take offs from craigslist for 50 bucks, bought some Force Pro mufflers from Summit and had true duels fabed up for 90 total for labot and install of everything. Go true duels you be happier in the long run.
For price comparision, I just had a complete 3" dual setup fabbed up and installed with flowmasters for $450. That was parts, labor, everything. Took the guy about 3 hours to do.
It was a shop that was under a place called "lakeway tire". Basically like a modica bros or discount tire.
To the OP: One thing to consider before making your choice is the plans you have for the car in the future. If you plan on other performance mods (headers, cam, supercharger, etc) then you need to go dual, if not, single splitting to dual will be fine.
If you decide to go dual, you may want to consider using an xpipe or hpipe also. Divorced duals can sound pretty nasty on a 6er.
i say go dual b.c u never know if you'll want to do other performance mods or not... i mean why not do it to be on the safe side... instead of doin some single and then later on down the road u want to do a performance mod but won't get the best of it cause your exhaust.... just do it to be on the safe side, u REALLY have nothing to lose my friend
well i mean its a 2004 but its got 90,000 miles on it plus its an automatic so im not trying to turn it into a track car plus i have to start worrying about college next year as it will be my last year in highscool. the only mod i have planned for it at this time are the exhaust, a tuner, and a cold air intake.
tell me if im crazy but wouldnt it be cheaper to just by an h pipe then insert some cat's and find gt takeoffs with the flowmaster super 40s already in it. or to buy a catted h pipe
