Spf Exhaust

[efrost]

Depending on your engine combination.... if you are running a 400'ish small block I would doubt it but I am basing this on what I have read and in talking with a couple SPF dealers not personal experience. The expense of hacking up your side pipes, welding in new collectors and mufflers then having the new sidepipe/mufflers recoated is quite expensive with little reward. Cost per horsepower appears to be very high. Having said this if you are looking for a certain sound well that is a different story.

There are one or two fabricators that specialize in SPF header/sidepipes that may be worth looking into. There is a spirited thread or two on these fabricators. My understanding is that a quality product can be purchased for a price.

Now if you are running a BB or a stroked BB there may be significate HP to be gained from a header/sidepipe swap.

Depending on your engine there may be other options to produce the elusive HP/TQ number we all search for. Details are needed

Others with real world experience will pipe in soon.
