Long tube headers install questions

[McDG8]

Hello all, new to the forums. I have the 09 g8 gt, currently with a k&n cai, and a borla cat-back s-type exhaust. My question is, I am replacing the stock manifolds with pacesetter long tube headers, what other items will be needed (I know the outlet of the headers is 3in and my exhaust is 2.5 in so I’ll need a reduced) but what else is needed? Also, will my exhaust match up without modifying or adjusting it? Loving this car and I’d prefer to do most of the work myself on it.

Your best bet is to get the reducers and get a good exhaust shop to do the work. You need the pipe benders and a good neat welder to do a nice clean job.
