4L60E and exhaust woes

im currently fabbing my exhaust y-pipe and back. I've got the STOCK ls1 exhaust manifolds, so the flanges sit up higher than long tubes would like most people have. I've also got the larger 4l60e vs a manual trans, which would have freed up more space in the tunnel. Anywho, I'm trying to run my two banks over to the passenger side floorpan area to meet them together. But they will interfere with my SFC crossbeam over there...

Anyone have any pics of their exhaust on the same setup or am I SOL on ground clearance? lol should i just make something that works, or try to find a good routing path and tuck it up for clearance...my options are running out it seems.

Thanks!

Re: 4L60E and exhaust woes

i've got one of pocket's old setups (for now, mid-length hedmans on the way) and it fits a 4l60e. however, i dont think you'll be able to take your pipes over to the psgr side the way you want to. the y i have comes together after the trans due to spacing, but doesn't lose any ground clearance. however, as it sits, it required a custom trans cross member and there doesn't look to be room for a properly placed cat

hawks double hump crossmember would be ideal for you.... this is my setup using a the same exhaust system for my t56 and 60e i previously had....

Re: 4L60E and exhaust woes

T56 is much easier. I'm running long tubes w/ my auto trans and I had to cut and piece together a lot of small pieces and different angles to squeeze between and under the trans pan and the frame rail. You just have to try to keep the pipes as high as you can and the crossover has to be in back of the trans.
