G8 exhaust to PPV
Posted: Mon Jul 30, 2018 8:18 pm
Fuzzkill already did this and had pictures, but just wanted to post up my own experience.
I bought a system made for the G8 after getting some feedback. He did some quick welds to the joints (slip joints with about 4" or so to accommodate the other pipe) and obviously extended the tips. I asked him about what else he did to make the exhaust fit and if in his opinion it could be accomplished with just some extra lengths of pipe slip fit. He said he didn't feel it would be an issue and he was correct. Besides needing only about four extra inches where the x-pipe and under axle pipes meet, everything else bolted right up. The inlet pipes off the stock cats to the x-pipe section fit together fine with plenty of room to spare and a good seal on the connections. The tips need to be extended about 6-6.5" depending on where I want them to sit in the rear bumper.
If I had the length on hand of piping needed, this would have been a simple unbolt and install affair. Though on my car unbolting the exhaust was anything but easy, and if your car has any appreciable amount of miles in the rust belt, good luck. I threw a lot of heat at these bolts AND the connections to the stock cats.
As an aside... the sound of a dumped x-pipe coming from a car that looks as pedestrian as my Caprice made my wife laugh.
I will throw up some pictures when I get into work tomorrow.
