I have a SLP setup with 1 3/4 longtubes with high flow cats. I have recently swapped a ls7 and these are probably too small. I made 470 RWHP with these on a mustang dyno and TI exhaust. They have less than 4K miles on them and are in near perfect shape with even a 02 bung welded for wideband.
just to let you know, few members here did upgrade to 1 7/8 and did not lost any troque and HP numbers even at low rpm range. so keep it. GL on whatever you decide.
I have LG Pro 1 3/4 headers, ceramic coated, AIR pipes deleted with off-road x-pipe that i was planning on selling and purchasing a set of 1 7/8 headers... this might be a good alternative for both of us?
Still available for sale and trade. Really looking for a full emissions setup, but will still consider trade if the x-pipe is catless, but the AIR tubes are there.
Shipping is expensive due to the one piece x-pipe, so trades are tough unless you're close to NJ or have a full emissions friendly setup.
After way too much thinking, I decided to buy a set of XS Power 1 3/4 cus I really wanted cats. These are now for sale...good deal...$900 shipped or $800 picked up.
