probibly because your o2s are gonna be to exposed?

I would put some kind of x or h pipe in there to equalize the pressure between the banks. Other than that its not too much different than a normal true dual setup.

he is running a y pipe

im running that currently, sounds loud but good, however duals sounded way better

uhh that's basically my setup.... shorties into a y, into a LM resonator, then dumped

in a month I'll be runnin' lt's into TD X pipe, and then each pipe into a LM resonator, then dumped

That is more than enough. It would be like running a permanent cut-out.

so far noone has given me a reason not to do it .

No they won't the O2's are in the headers, he has a lenght of tubing to a Y more tubing a muffler then a tip.

A mid pipe is not to equalise pressure it does two things, firstly reduces db levels buit more importantly scavenges.

A good Y pipe will scavenge in much the same way as an X pipe.

Well you can do this, bu in all honesty it really isn't different to most catbacks. Such as a SLP LM or TSP Rumbler.

They go headers, Y pipe, muffler then over the axle and generally split into two outlets. But the extra tubing over the axle will not have any great affect on the performance of the exhaust.

Personally I would either run it out the back (you could even keep it as a single pipe if you wanted). But if you want to dump before the axle I would just swap the Y for a X pipe and have two smaller mufflers, one per bank.

It's not that dual will offer any more power on a bolt on/cammed LS1 but if you go FI it will outflow a 3" Y pipe. Also duals sound arguably better than Y setups.

yeah one of my friends had the setup on his camaro but he had a 408 It sounded badass. The only thing he did was he had a 4 inch pipe coming straight from the bullet right to the rear end and wasn't dumped. It was loud as hell sounded like a race car on the street. but i am sure it was because of the 408 he had.

I say try it out man i always wanted to do the same but i use my car to drive to work

One guy on here has a 3" y-pipe with 4" flowmaster merge, then 4" bullet, then 4" turndown. I cannot find the thread for the life of me! Can anyone dig it up? Remember which user it was? I would appreciate it greatly.

Yeah I remember that thread, pretty sure it was a mod who posted though.

i have a 3" y, then 3.5" pipe going into a bullet, then a single 3.5" pipe out the back. i put the bullet in the same area where the stock muffler was. it is extremely loud.
