[ZeroC]

So to start i have had 3 sets of tsp headers in different cars
First set was in my 2011 camaro ss 1-7/8 fit beauty had zero problems

Second set was on my 2000 Trans Am 1-7/8 and they fit horribly needed lots of "clearance" "work" - contacted tsp they blamed the stock motor mounts makes sense - replaced all the mounts with poly - same issue had to do alot of denting on headers and body - but they eventually "fit"

Third and last set 2018 camaro ss - went with the 2 inch due to the added blower i replaced the motor mounts with bmr polys to avoid any "issues"
however they still had problems :(
they rubbed the steering shaft bolt top and bottom bolts not just the lower one they say may hit

replaced with button heads the bolts clear now but just - the upper potion of the the steering shaft just below the top bolt rubs the primary and binds up feels nice and safe when driving

the part i was not expecting was the header hitting the shear plate sits right on top and rattles like crazy

so i have to remove the driver side header and dent it which sucks since they are coated :( and im going to have my fab guy mod my shear plate to make room for the headers

next time i will do kooks or ARH

All the other threads where people say they had no issues and they fit fine had me in major cope mode lol

2 out of 3 installs sucked so take it as you will

best of luck anyway you go !
