A lot of long tube, mid length and even shorty headers won't fit classic Mustangs that have aftermarket power steering from Borgerson etc. I used stock style Scott Drake cast iron exhaust manifolds and they fit great. No notable loss of power or sound, but then I'm not looking for a few more HP.
I ordered shorty headers for my 20 GT. Dealers said they would not bolt right up. The catayltic convertors are connected to factory manifold for some stupid reason by Ford. Can you show a video of install of shorty headers on a 18+ Mustang GT
I just installed an H-Pipe on my '21 GT. Was I wrong in thinking LTH would bolt up without further exhaust modification later down the road? What are the obstacles that 18+ s550 mustangs face compared to 15-17? Thanks.
LTH headers will require a matching mid-pipe since it will be much shorter. The 18+ have the cat built into the header which makes shorties pretty much impossible without deleting the cats or a custom midpipe. The H pipe you have is most likely a resonator delete so it mounts in the cat back part of the exhaust system.
@@cjponyparts ah, I understand now. I was misunderstanding your terminology describing the exhaust when you spoke about mid pipe. Thanks for the information!
Do you have advice on which header will fit a 1966 Mustang with GT40p heads? Using factory 66 manifolds now, but would like something with better flow. Not looking for long tubes or interested in cutting the shock towers.
Shorty headers that are a direct replacement for your stock manifolds are legal here in Ca.. The position of your cat doesn't change with shorty's. Long tube headers are illegal here.in Ca. because your cat's position is "too far away from the motors head and won't get hot enough" to do it's job. " It's all B.S. but that's how it is.
