Various LNF downpipes DP
Read this thread, to learn more about these downpipes.
DP testing, the Ruthless Pursuit of Power - Chevy HHR Network
4 of the DP's in the picture, are for sale @ $100 each, + shipping, as I'm done with DP testing now...
1. Stock manual DP
2. Stock manual DP with 2" hole 'cored' thru both cats.
3. Stock manual DP with both cats 100% removed, with a piece of 2.75" tubing placed in the 2nd cat housing. The 1st cat housing was cut open, so that I could weld in a piece of 3" tubing. This housing was then welded back in place. So both cat housings in this DP, are now resonators. This is a stock appearing DP that is a quiet free flowing catless DP. This is the DP that I was using, before installing the present DP ,that I am now using.
4. CIA 9lb catless DP that has a single cut, in the middle. I paid $350 for it 2 or 3 years ago. This will fit both manual, or automatics.
1st 3 OEM manual type DPs, come with a 'dummy' O2 sensor, as shown in that picture.
