So my LS1 swap was completed last June. I was able to put about 2000m on the car before putting it away for the winter. Shook down a couple minor issues and overall she's running fantastic. I am pulling the diff tomorrow night and having my Stage 1.5 (3.93 final drive) Puddymod diff upgraded by Puddymod to a Stage 2 with 3.63 gears. The GTO comes with 3.46 gears so I'm thinking it will be a nice match with my S weighing in a lot less than a GTO with it's 3,725 curb weight.

One of the issues I'm having is the exhaust sounds like poo. I have 1.78" headers going to a y-pipe (cat-less for the moment) and then an Nvidia Q300 stainless cat-back modified with an ultra quiet resonator from when she was supercharged. It's raspy when I come off the throttle and overall just doesn't sound as good as it should. By the way that cat-back would be up for sale (for cheap) once I get a new exhaust installed.

I would like to have a custom stainless dual exhaust fabbed up with dual HFC's and an x-pipe. Can anyone recommend a reputable shop in the CT/Western MA area for this? It would be a huge bonus if they also did dyno-tuning since that's my next step after the exhaust. Thanks in advance folks!

Any pics?

Not sure what you want pic's of specifically. Here's my build thread w/pic's:

2004 Vortech S/C S2000 to 2004 GTO LS1/T56 swap

I'm gonna go get a quote from ECS Performance (ECS Performance | Connecticut's premier performance, tuning, and repair shop.) in Windsor Locks, CT. They are actually fabbing a stainless dual exhaust right now for an LS swapped 240sx. I might go see how that looks while I'm waiting for my Puddy diff. Anyone heard of them? Google reviews seem good.

I don't have any experience with ECS. Flatout Motorsports in Mendon, MA will do custom exhaust. I have used them for alignments, but they did quote me for a custom exhaust for my race S2000, when I had the last alignment done there.
