I saw one thread about issues with the tpis longtubes. It showed a pic of the steering linkage being directly in the path of the primaries where mine have plenty of clearance in that spot. I don't see a single spot where they had to be bent or clearanced to fit. The Y pipe is a different story, but I'm not sure what brand it is.

 

I will get some pics for you.

Yep. I have seen pacesetters on one car with tons of room everywhere and another that was very close.

 

Thanks
