I know a lot of you guys have been asking for side-by-side dyno data from when we did our header development & testing. I have attached a copy of dyno testing our TSP Z51 M7 car with only headers installed. The testing shows our header next to two major brands that also make C7 headers. I will not discuss which brands they are so please don't ask. The data was for development of our primaries & not to beat up anyone for their products. All 3 brands tested were of very nice quality & fit.
The dyno graph clearly shows the advantages to long primaries for torque production! The TSP headers have the longest primaries in the C7 header world & I believe are probably the most powerful headers available!
Look for much more data, install reviews & pics to come very soon as these headers are finally starting to reach customers for installs!!
When looking at these headers it does appear the primaries are longer than the competitors. Jason how hard would it be to add a v-band flange on the connection between the header and x pipe? Just never really cared for the slip fit design. Other than that love the headers from the pics, in for more results.
