Hey guys im new to this but had a couple of questions. I just installed my headers which took about 8 hours but at least i got it done! I didn't get any sims for the back O2 sensors because im going to get it tuned, will this affect my performance to much or should I get the sims till I get it tuned. Also I didn't notice much of a difference of acceleration/HP i think it is because of an exhaust leak would that be a major problem? Thanks for the advice guys.

the codes should have nothing to do with the preformance of your car. Give the computer a few miles to change its tune for the headers.

the sims are there to keep the code from being thrown. Its not going to affect the performance if you dont have any sims. Congrats on the install .
