Well Glad I got my answer before this went crazy.

i run tri-y headers and glass packs to dual side exhaust i like the sound very muscle car of 60's

Nice sound, you got going there.

TomKat

thank you i appreciate it a lot! I used to run the flowmaster 40 series but couldn't stand the tone it made. I'm much happier with this set up and it looks clean just like the GT350

kenash

Yeah, I considered the side exhaust too, but, with my lowered frame and unless I flattened them, I would have dragged them on many a bump.

Sounds amazing TomKat! I really think I want to go with the tri Ys for the ease to install. I am not sure about side or dual straight back. I am loving this thread and think it would be a cool one to get bigger. Ill change the title to "Lets Hear your Exhaust roar!" or something like that!!!

can the standard cast iron exhaust manifolds be ported/ground out to achieve the characteristics of the hi-po ones? i use to run full length headers and always had trouble with power steering lines getting burned up on them.

Hi,
"can the standard cast iron exhaust manifolds be ported/ground out to achieve the characteristics of the hi-po ones?".....Not really.

The Hi-POs are shaped differently, so as, to flow better than stock. They are your first best choice. IMHO, the TRI-Y design is the best header for a well thought out street warrior engine. But, these still require the installation of the power ram drop bracket.
Good Luck with your project.

can i port/grind out standard cast iron manifolds to get the characteristics of the hi-po ones? i use to run full length headers but always had issues with the power steering hoses getting burned up on them. looking for a different set up. also considering shorty headers.
thanks.

tri-y are really good for the performance and they are period correct win win in my book
