Headers & Tune - Happy Customer!
 

Just had LG long tube headers installed to my nearly stock 2006 Z06.

Install and tune was done by Manny @ Dasilva Motorsports in Kitchener, Ontario. If you're even close to local, I highly recommend them - very patient with answering my questions and top notch workmanship!

Now onto the fun stuff.
Baseline results: 468whp and 405lb-ft. This is on a dynojet on a 30* C day near Toronto (too lazy to look up elevation!).

Car has 42,000km and has re-machined OEM heads with bronze valve guides, stainless valves and Brian Tooley double springs, a K&N intake and the OEM muffler mod. Very happy with the baseline whp!

After: 482whp and 458lb-ft.
The +50lb-ft is sweet but what's more important than the peak gain is the 'area under the curve' that comes from having a big gain over a longer rpm band.

Car runs great and sounds absolutely insane.
I read mixed reviews on doing headers only (without a cam) but thanks to a local deal ($950 for fairly mint LG headers with catted xpipe and all accessories), I pulled the trigger and I'm glad I did!

Next up - DRM Bilsteins, which Randy says should be shipping shortly!
