Do I need to seal the joints where the tubes connect?

Clamps alone create a mechanical seal, but adding silicone sealant or intercooler-rated epoxy around the connection points eliminates micro-leaks. It's not required but common for boost systems where you want zero air loss.

Can I cut and reshape these tubes to fit my engine bay?

Aluminum tubing can be bent and cut with standard tools—hacksaw, bandsaw, or angle grinder work fine. Sand or file the cut edges smooth before assembly to avoid damaging O-rings or seals at connection points.

Will these tubes handle higher boost pressures?

Aluminum tubing is rigid and handles moderate boost well, but pressure capability depends on wall thickness and how tightly you clamp the connections. For extreme boost levels, reinforced or mandrel-bent tubing is a safer bet—test your setup before pushing it hard.
