I didn't want to put this post in the "tech" area because its not a technical problem. Just need some opinions. I have a 67 cougar with a 92 ford mustang engine efi with bbk headers. I bought a x-pipe (no cats) and bought the 17281 american thunder flowmaster exhaust kit (comes with hpipe no cats). The kit is hung except this problem. I will say since I did the ford explorer rear end swap in it, I was surprised I do not have to shift the exhast over at all. There is plenty of room there. Well I knew there would be welding to do. I have 2 options.....
The bbk xpipe came in 3 pieces. the actual x pipe itself and 2 pieces that go from the headers to the pipe (kind of like a down pipe). The h-pipe has the same set up except no flanges.
1) I can take them "down pipes" and weld it onto the H-pipe provided by flowmasters kit and the rest of kit fall right in place.
2) I can put on the bbk x pipe, hang the kit....BUT, the intermediate pipes (go from the muffler to the h pipe) are too short. So, I would have to get 2 new pieces of pipe made to work. I would also have to cut the back flanges so I can but them together and weld.
What are you opinions??? I have the skills to do both. I have built my engine with edelbrock up, stroked it to 347 with scat. I have dumped a lot of money into and want to get as much horsepower possible. What produces more HP, the h pipe with no cats or the x pipe with no cats? I googled that and it seems to me a lot of 16 year old kids were making up stories! Thanks for all the help!!!!!
