Re: SL55 Y-Pipe vs. Stock SRT Y-Pipe (for intake, not intercooler)
Shawn,
It will be interesting to see how you fab it all up.
I have a quote comming my way for all the parts necessary to upgrade my ride with:
1) A complete SL55 AMG V8 intake system. Air boxes, K&N filters, Y-pipe, air hoses etc..
2) A 185mm Overdrive Crank Pulley (with all the fixin's) to provide 25% SC boot.
Now that headers are out for the near future, if the price is right - I will order both this week.
