Hey sorry to bother you..But I currently have LM II and was thinking of doing the full SLP exhaust. The only thing is I want to but it in stages. Do you think its possible to buy the crossover X pipe that bolts on to my stock headers and later onb buy the SLP headers? Will the SLP headers bolt on to that system? or do I have to wait until I can buy the complete system all at one time? Has your exhaust thrown any codes? Anyways any help would be awesome, and your camaro sounds SICK by the way!!
