You know where the exhaust mufflers bolt to the end pipes? I have them disconnected. They are hanging with zip ties to make it look like i have exhaust tips. I tried to explain it in my second paragraph, the exhaust is shooting some sound into these pipes a little and you hear it until im at full throttle. I dont have any exhaust leaks

new exhaust setup
I cut the aero turbine mufflers out and installed some 13 inch long borla resonated tips and adjusted my J pipes shorter by 8 inches. the result is a nice mellow tone and no more drone. my suspicion of the aero turbines being large resonant chambers has been confirmed. the car is enjoyable to drive and is basically straight piped. I have the aero resonators still in place after the x pipe but thats it for any sound deadening. Oh! and the cars low end torque came back with a vengeance. the wheels broke loose like a **** when I barely touched the throttle so very pleased with the results.

Sounds fricken awesome man, yeah I'm still looking for different mufflers or maybe even this would be a good idea for me as well. How did u figure out the length for the j pipe? That is new to me

Just wanted to drop in and say great build so far and hope you continue posting more, keep the forums alive.
Hope you can come up with a solution to the slow shifting issues. Would you recommend the torque converter upgrade for a stock car? drive-ability suffer part throttle?

Your build looks great. Just popping in randomly on CL. I was looking to see what V8 progress anyone has done since the last time I was really active on here, which was probably 4-5 years ago lol. I am planning to do a V8 build in the near future. 1UZ VVTi with forged internals, single turbo, and standalone.
For your VB shifting issue you will need the control valve for the 1-2 shift modified internally. Most trans builders do not to the 1-2 on the A650E. Maybe they haven't found out how to do it yet? My 1-2 shifts are hilariously quick. As in smoking the tires into 2nd gear after shifting out of 1st. On the built GS300's we build at my shop, I believe I have found the uppermost limit for the A650E. The highest I have been able to push through it so far is 960whp/805tq on the dyno. I couldn't get the dyno to load up the car enough to get more than 36psi boost. I know we probably have eclipsed 1000whp mark on the street with 45psi boost. However, the transmission is really hating life at that range lol. Just saying the A650E has a lot of potential that most people don't even know is there!

thanks for the complement. I've had in my car for the longest time a much firmer spring and aluminum spacer for the B-2 accumulator that is for the 1-2 shift. ill pull the vb back down and put that spring in there and see if it helps. maybe while the vb is down ill get into the 1-2 control valve. i have literature for the vb that lists all locations of control valves along with spring sizes and coils etc.... I'd like to roll up there sometime and check out your operation. plus we should go racing. ill bring a go pro.

I must say, I love to come back to this thread every month or so to see what else you've done to your GS! I actually just got a GS430 in August and I think I might start planning to go this route with my car. I was also curious about how you figured out your J-pipes and why they needed to be shortened.
